STM32F407IGT6: Device not flashing

[banuprathap]

Hi,
I am unable to flash the compiled file. I am using STM32F407IGT6 on a custom board. It shows stlink_fwrite_flash() == -1 error. I tried reinstalling stlink but to no avail.

• Programmer/board type: Stlink/v2
• Operating system: 4.4.0-96-generic # 119~14.04.1-Ubuntu SMP i686 GNU/Linux
• Stlink tools version and/or git commit hash: 1.4.0-9-g6511a7e
• Stlink commandline tool name: st-flash
• Target chip (and optional board): STM32F407IGT6
  A as-detailed description possible of the problem with debug output when available.

Output:

It was working fine couple of days ago but wouldn't work anymore. Am I doing anything wrong?

Thank you!

Flash loader problems are hard to debug. Maybe you can find some usefull information from other open and closed issues by filtering: https://github.com/texane/stlink/labels/error%2Fflash-loader.

I had a similar problem with a STM32F446RET6 (writing at address 0x8000000). After a mass erase it started to work.

Please verify if problem still exists in Release v1.6.0.

[banuprathap]

I tried v1.6.0 as I couldn't find v1.6.1 and it seems to work now. Thank you!

[Nightwalker-87]

v1.6.1 is only the milestone of the next upcoming release. Nothing to worry about. You did everything right! Thank you for your feedback - very helpful to us. :-)

Reopening this as the underlying problem that causes this issue remains unsolved.
