Q12.How can I check the CPUs that can be used with the FP-10 that I own?
A12.Connect FP-10 to the host PC, run C-Flash, go to the Help menu, select [Information]. In the Product information dialog, the CPUs supported (both usable and unusable) are displayed. Usable CPUs appear to be dark(enabled) and unusable CPUs are displayed in grey(disabled). Please note that unusable CPUs can be used by purchasing a CPU update license. New CPUs are added in every software release/update and may not be displayed in the version you are using unless you update C-Flash to the latest version. Check our homepage for latest information about supported CPUs.
Q13.I have multiple FP-10s and the list of CPUs that are usable and unusable are different on them. How is that possible?
A13.The list of usable and unusable CPUs is FP-10 specific and depends on the License reference date. License reference date is the date on which the first license file was registered or the date on which a CPU update license file was registered. If the license registration update date is different for the FP-10s, the usable and unusable CPU list may differ.
Q14.I have updated C-Flash to the latest version, but the CPU displayed as supported in the CPU search on the homepage is not displayed in the usable CPU list of C-Flash, why?
A14.The CPUs that are usable on FP-10 depend on the License reference date displayed in the License information. The License reference date is significant because the CPUs supported by the version of C-Flash released on/before the License reference date are CPUs that will be usable in FP-10. License reference date is the date on which the first license file was registered or the date on which a CPU update license file was registered. Please purchase the CPU update license and register the license. This ensures that the License reference date is renewed and the new CPU(s) will be usable in FP-10.
Q15. How do I update C-Flash?
A15.The latest version of C-Flash can be downloaded and installed from the License Tool Update Wizard 2 for free. Please be aware that CPU update license would have to be purchased for using newly supported CPUs.
Q16.How do I update C-Flash if I have no internet access?
A16.Normally an internet connection is needed for updating C-Flash. However if internet connectivity is not available, C-Flash can be updated using the setup files downloaded on another PC that is connected to the internet. Follow these steps. On a PC that is connected to the internet, install the License Tool 2 and run the Update wizard. At the last stage of the wizard, open the folder where the setup files have been downloaded and transfer them to a storage device. Copy the file(s) to the offline PC and run the setup file.
Q17.Where can I ask technical questions on using FP-10?
A17.Please use the user support site for technical questions. Fill in the questionnaire and fill in details like usage environment, your questions etc. and contact the Technical Center (support@computex.co.jp).
For smooth support, it is recommended to send screenshots of the specific phenomenon if any, C-Flash project file etc.
Q18.When using FP-10 in standalone mode, can you supply power from a PC?
A18.No, FP-10 automatically changes to C-Flash mode when connected to a PC. Hence, it is not possible to supply power to FP-10 from a PC in standalone mode. Please use the supplied AC adapter when operating FP-10 in standalone mode.
Q19.Can I control FP-10 with an external signal?
A19.C-Flash Ver. 1.38.00 or newer provides External Input/Output function for FP-10.
An input signal line for writing to FP-10 and an output signal line to output the writing status are used. Note that the completion/failure of the write operation can not be detected by an external signal.
Q20.I'd like to change the computer on which C-Flash is installed. Do I need to follow some procedure for migration and moving the License?
A20.When FP-10 is used for the first time, the required information pertaining to license etc. are copied on to the FP-10 unit eliminating the need for any migration/manual copying of files when the host PC is changed.
FP-10 can be used as is after installing C-Flash(available as a free download) on the new host PC.
Q21.How is C-Flash update notified?
A21.No notification for C-Flash version update is provided. Please check if there is an update for C-Flash in the license tool Update Wizard 2 manually. The latest version of C-Flash can be downloaded and updated any time for free.
Q22.What is meant by the term "Device ID" of FP-10?
A22.The Device ID is an ID for uniquely identifying each FP-10 when multiple FP-10s are connected to a PC and is used by C-Flash for controlling the specified FP-10. Please make sure the Device ID is unique for every FP-10 when multiple FP-10s are connected to a PC. The device ID can be changed from the product information screen and is set to 0 (zero) at the time of shipment.
Q23.Please tell me the write sequence of FP-10.
A23.The basic write sequence is as follows:
Data comparison on C-Flash and FP-10 → Upon data mistmatch, update data in FP-10 → CPU initialization (including protect/security release) → All Erase → Write → Verify → Check SUM → Set Protect/Security.
CPU initialization will issue a reset from JTAG and cause the CPU to Break. Before CPU break Protect/security cancellation is performed. This also occurs during C-Flash startup and hardware initialization.
Q24.Can I change the buzzer volume and tone on FP-10?
A24.No, the buzzer volume and tone are fixed and can not be changed.
Q25.Occasionally, FP-10 fails to start up or fails to write. Is there anything that I need to take care of?
A25.FP-10 has been tested rigorously and is known to work without any issues. Communication between FP-10 and the CPU is performed in synchronization with the JTAG clock through the JTAG/SWD interface. Make sure that you are using the standard cable provided for connecting the target to FP-10. Operation is not guarenteed otherwise and no user support will be provided. Make sure the connectors are well connected and the right power adapter is used. If the problem persists, contact us through the user support site. Refer "Q17. Where can I ask technical questions on using FP-10?".
Q26.What is the cause of the error "Hardware initialization failed"?
A26.This message indicates an error during target CPU initialization and is displayed when JTAG communication can not be performed due to unexpected power problems, CPU shutdown, internal reset (WDT), external reset, security, pin setting, etc. The CPU may also display this message if it is not properly initialized after JTAG reset. Please be informed that if the CPU hardware initialization fails, none of the processing can be performed. Make sure the target CPU power supply is OK and that all cables are secured. If the problem persists, contact us through the user support site. Refer "Q17. Where can I ask technical questions on using FP-10?".
Q27. When writing with FP-10, there are times when the writing time differs with the same CPU, why?
A27.The writing time of FP-10 depends on the following factors:
1. Data update time of the FP-10 unit - If there is a difference in the data stored in C-Flash (memory on the host PC) and the data on FP-10 flash memory, data is updated on FP-10 and then written to the target system's flash memory. If the same data is written again, the data is not updated on FP-10 leading to a time difference.
2. Skipping Write due to data content - If the write data has many blanks (flash memory erase value), write is skipped leading to a shortened write time. Write time would be more if write data has fewer blanks.
3. Initialization/clock issues - If write is performed when the CPU is in uninitialized state or if the clock is changed by the internal program that is executing on the CPU, the time needed to write may differ.
Q28.When writing a program file, can I preserve the previously written program and write the new program file to another address?
A28.No, C-Flash/FP-10 do not support preserving contents and writing to flash memory.
Q29.Can I write only by changing some of the contents in the area?
A29.No, FP-10 is designed to write the data set in C-Flash. Some parts in the write area or only a part of the area can not be changed.
Q30.When writing to FP-10, can I write without erasing?
A30.Yes, this can be done from C-Flash. Go to [Set] [Target system settings] dialog [Memory operation setting] tab [Write] and uncheck [Erase]. Please be aware that data will not be consistant if write is performed without erasing flash memory which already has data on it.
Q31.I am using an erased chip, can I skip erasing?
A31.Yes, this can be done from C-flash by unchecking [Erase] under [Set] [Target system settings] dialog [Memory operation setting] tab [Permission of the write operation].
Q32.Can I perform verification only?
A32.Yes, this can be done from C-flash by unchecking [Erase] and [Write] under [Set] [Target system settings] dialog [Memory operation setting] tab [Permission of the write operation].
Q33.Can I skip the verification?
A33.No, verification is compulsary to detect write errors if any and can not be skipped.
Q34.Can I display the value of the check sum at the time of writing?
A34.Yes, this can be done from C-flash by checking the [Display the SUM value after writing into the flash memory] under [C-Flash Settings] dialog [Display] tab.
Q35.Can operations be performed on the security function of the CPU?
A35.Yes, CPU Security can be set and released from C-Flash. Please be aware that due to manufacturer restrictions, there are cases when JTAG is prohibited from cancelling CPU security.
Q36.While using the socket communication application to write, a message stating that the target can not be found is displayed every time the target is turned off. How can I prevent this message from being displayed?
A36.This message can be prevented from being shown by executing "ProbePowerCheck(false)" command on C-Flash Ver. 1.13.00 or later.
Q37.While using the socket communication application to write, when I change the host PC I can not control the FP-10, why?
A37.It may be due to one of the following reasons:
1. Restrictions by security software
Review security software/antivirus settings such as allowing port access for both server and client.
2. Restricted by firewall
Review "Port used" under Windows firewall or the security software.
3. IP address changes by DHCP
If the IP address keeps changing, try setting static IP address.
Q38.Is it possible to change the Option byte of STM32 series?
Q39.In case of EFM32GG, when erasing or writing to internal flash, the current consumption can be set to low power or normal mode. Which mode is used by FP-10?
A39.FP-10 uses normal current mode and not low power current mode when erasing or writing to the internal flash of EFM32GG.
Q40.Is there a way to write to the Boot area of Atmel ATSAMS70?
A40.On SAMS70, when bit 1 of GPNVM register is 1, 0x00400000 address corresponds to the bootloader start address. So, specify 0x00400000 as the offset address when the load file is specified on FP-10. This will write the file to the boot area.
Q41.How do I apply for repair of FP-10?
A41.Please contact the vendor/place of purchase about repairs.
Q42.Can I transfer or resell FP-10/C-Flash?
A42.C-Flash or FP-10 can not be transferred or resold. Reselling, renting, leasing out, or giving C-Flash or FP-10 to a third party is considered a breach of the Software License Agreement (The Software License Agreement is displayed when C-Flash is installed).
Q43.When using XMC1000 series, is it possible to write even when BMI is ASC_BSL?
A43.Yes, it is possible to write even when BMI is ASC_BSL.
Using UART BMI can be changed. Please contact our sales department for details.
Q44.Is it possible to use the SW1 of XMC1000 series?
Q45.Is it possible to use the SPD interface of XMC 1000 series?
A45.No, SPD interface is not supported, please use the SWD interface instead.
Q46.Are there any precautions to be taken when migrating from FP-10 to FP-10(model PS)?
A46.FP-10(model PS) is backward-compatible and can be used instead of FP-10 without any issues. Please check "About FP-10 (model PS)" on how to use the additional features and about GND connection.
