Expected/description:

I reviewed all issues related to this “Unknown memory region”, many of them point to a bad cable connection between st-link and bluepill (SCLK SDIO), but, i tested everything on windows 10 too, and i am able to flash successfully, so connection must be fine.

Everything else seems to be well recognized, as:

 st-info --probe

openocd: "\x37\x1a\x0b\x00\x2c\x13\x57\x37\x33\x4d\x4e\x00"
  flash: 0 (pagesize: 1024)
   sram: 20480
 chipid: 0x0410
  descr: F1 Medium-density device

Maybe is my fault, but i don’t know what else to do, i even installed everything from scratch in a different ubuntu machine (18.04) with same results.

Thank you for your support.

Hmm, I wouldn’t assess that writing concluded successfully:

020-09-29T19:26:38 INFO flash_loader.c: Successfully loaded flash loader in sram

3/57 pages written

2020-09-29T19:26:38 ERROR common.c: stlink_flash_loader_run(0x8000c00) failed! == -1
stlink_fwrite_flash() == -1

We need some improvement here as well. 😕 I’d need a STM32F1C8T6 Bluepill (Note: Not to be confused with STM32F1CBT6 !) with 128k to look into this. Mine only has the standard 64k flash.

For me, everything works as expected with v1.6.1 on Ubuntu 16.04 with a bluepill:
