STM32L496G discovery kit - st-flash write does not work - flash loader run error #657
Description
- Programmer/board type: Stlink/v2-1 onboard
- Programmer firmware version: V2J28M18
- Operating system: Linux 4.13.0-1-amd64 # 1 SMP Debian 4.13.10-1 (2017-10-30) x86_64 GNU/Linux
- Stlink tools version and/or git commit hash: v1.4.0-13-g1969148
- Stlink command line tool name:
st-flash - Target chip (and optional board): STM32L496G discovery kit
I cannot use st-flash to write an image on linux. By now, I use Windows to do this. I can see these information in the STM32 ST-LINK Utility when I click on "Connect to the target." button:
11:29:41 : ST-LINK SN : 0674FF555352845187081728

11:29:41 : SWD Frequency = 4,0 MHz.
11:29:41 : Connection mode : Connect Under Reset.
11:29:41 : Debug in Low Power mode enabled.

It works pretty well on Windows (Windows 7 Pro) but I need to hold on the reset button when I plug the board to the USB port of my laptop. If I do not, the ST-LINK program does not work well. I do not know why I need to do this but I saw on Internet few month ago a guy talk about this hint and since I use this trick. A colleague with the same board and a different laptop (with Windows XP) can use it without this trick. Pretty weird. Perhaps, this behavior can explain why I cannot use st-flash on linux ?

If I use the option --debug, there are extra information. I put the output in an attached file: write_debug_out.txt
After trying to write an image with st-flash, If I plug the board on my Windows laptop and try to start the board with ST-LINK_CLI.exe, nothing happen:

I hope the information will be enough to help me.
Thank you,
