Hi, I trying flash stm32 device but no using Keil. I Try it successfully on Ubuntu.

For Windows, I run into some error:

c:\Users\chen>py Documents\pystlink\pystlink.py flash:erase flash:xpfw.bin
DEVICE: ST-Link/V2 V2J21S4
SUPPLY: 3.26V
CORE:   CortexM0
MCU:    STM32F042x6/STM32F048x6/STM32F070x6
FLASH:  32KB
SRAM:   6KB
*** Error unlocking FLASH ***

but when I try it again with -d param:

pystlink.py flash:erase flash:xpfw.bin  -d > stdout.txt 2> stderr.txt

nothing in stdout.txt, and here is the content of stderr.txt :

hello, please try first update firmware in ST-Link, on my configurations it is OK (Linux and Windows7) my version of ST-Link is: V2J27S6

chenwq3 commented 7 years ago

I updated the firmware of ST-Link debuger, and the problem still exist. The version of firmeware of ST-LINK debuger is: V2.J28.S7

pavelrevak commented 7 years ago

OK, if on Ubuntu is flashing successful, can you send me also log from Ubuntu and then again from Windows on same micro-controller with same flashing command for comparison? And be sure that you have same version of pystlink. (Please send logs as attachment if it is possible). Thanks.

I tested and I found that :

I will update if i get more information.

chenwq3 commented 7 years ago

For now, No more information. I will update if I have useful info. Close for now.

pavelrevak commented 7 years ago

probably is necessary to FLASH under reset, because the SWDIO pins are used by application and this feature is not implemented in pystlink right now.
