  • Programmer/board type: [genuine STLINK-V3SET updated to latest version V3J7M3B5S1]
  • Operating system and version: [Parabola GNU/Linux-libre, rolling release operating system updated to the latest version]
  • stlink tools version and/or git commit hash: [v1.6.1/git-ee491d9]
  • stlink commandline tool name: [st-flash]
  • Target chip (and board, if applicable): [genuine STM32L152RE]

Since pull request #1124 merged in revision v1.6.1/git-ee491d9, when issuing «st-flash write FIRMWARE.bin 0x8000000» I get an infinite bunch of «WARN common.c: Flash base use default L0 address» cluttering the screen and firmware is not flashed. It works in the previous revision.

@dariox86 Can you test https://github.com/Ant-ON/stlink/tree/l0_soft_loader_fix branch?
Can you provide full log of flashing operation?

Tested with https://github.com/Ant-ON/stlink/tree/l0_soft_loader_fix branch.

Thanks for the very detailed review! I have not been able to understand the reasons for this behavior yet. But I fixed one bug that was there. Can you test the https://github.com/Ant-ON/stlink/commits/l0_soft_loader_fix branch again?

@Ant-ON, I am glad my report was helpful. It works! Thank you! In aa70b89 I experience the usual issue with «WARN common.c: Flash base use default L0 address». After your commit in 679ab65 it works. It is also much faster! Before that it took maybe a couple of minutes. Now it's a matter of seconds.
