Hi, I have added the following lines in the DEVICES array in stm32devices.py under 'part_no': 0xc60 for the STM32G0B1RET6 support and it seems that it is working for me. I am not quite sure about the settings I choose for this part number, could you please double-check and let me know if I missed anything? Specifically, I cannot find information about the flash size register address (0x1fff75e0), the flash driver STM32L4 and the erase sizes:

'part_no': 0xc60,
'core': 'CortexM0+',
'idcode_reg': 0x40015800,
'devices': [ { 'dev_id': 0x467, 'flash_size_reg': 0x1fff75e0, 'flash_driver': 'STM32L4', 'erase_sizes': (2 * 1024, ), 'devices': [
{'type': 'STM32G0B1', 'flash_size': 512, 'sram_size': 144, 'eeprom_size': 0, 'freq': 64}, ], }, ],

i got *** Operation timeout *** error after execute this command my MCU is STM32L073RZ ?

Hi

I am facing issue with flashing the mcu with new credentials using sigfox flasher and st link 32 utility with python(py charm) but i am able to do it manually with the command prompt but getting the error while executing with py-charm.
Below is the error mentioned:

I/O error(13): Permission denied

FYI:
I am running this command using command promt as administrator and also running py charm with administrator rights.

below is the command i am using :

SIGFOX_FLASHER"FEDCBA98;0102030405060708;0123456789ABCDEF0123456789ABCDEF;1;-1740;0;0" -e fixed -k 995511775533664400AABBCCDDEEFF00 -f D:\nishant\ID_PACK_Key.bin -w

output on command promt.

Encryption succeeded.
STM32L0 found. Programming...
Programming completed.

Please help me as i am struggling with this since very long time and not getting any solution.

I am getting this error:

*** Parameter error: 'NoneType' object has no attribute 'bInterfaceNumber' ***

I am just running:

python3 pystlink.py flash:erase flash:verify:0x08000000:/home/automation/Downloads/ss2_firmware.bin

Note: I tried running via sudo and still same issue. I am running on Ubuntu 18.04.

Hi, great work on this implementation.

I'm in need to use this as a library in a python program I'm working on. I was able to take the lib folder, rename it to pystlink and change some imports from lib. to pystlink. and make it work as a library.

I see that pip install support is in the planed features. I think it would be a good idea to split the project up into two parts pystlink (library) and pystlink-cli (this application). That way pystlink-cli could just have a dependency on the library. I belive the library will need some improvemnets to make it easier to use and so on but I think this would be a good first start.

I want to avoid forking the project and doing it myself as I belive it's is better to focus on improving the original project. Thoughts?

I'm looking for a way to determine if the link between the ST-Link and the target is broken. So far, the only way I've found is to update the target_voltage reading. I expected coreid to update if the link was unplugged but instead it seems to report a cached value. I want to do this to automate firmware downloads in a test fixture so that if a new target board was plugged in, a firmware download would automatically begin, similar to the auto-download capability of the ST-Link utility. I'm using Windows.

I think I am missing something obvious. My ST-Link/V2-1 can be detected by the ST-Link Utility. What are the possible reasons I am having this issue?

Im getting this (first time):
*** USB Error: [Errno 32] Pipe error ***
and then this (every next time)
*** USB Error: [Errno 110] Operation timed out ***

I really don't know where to start

flash:erase:verify:address:bin will raise *** Parameter error: 16384 *** when writing bin file to address which already contain data

But if I using flash:verify:address:bin without erasing it, Verify error at block address will raise...

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

I tried to upload short program to SRAM by using upload command like this:

python3 pystlink.py upload:bytesWrite.srec

but it gives me error

*** Bad param "upload:bytesWrite.srec" ***

When I look into the pystlink.py, it looks like upload command is not implemented in cmd method...?

@UweBonnes make great work, but now I see that his patch don't work with STM32F0 (I don't make tests with other FP MCUs before merging)
Currently is the code reverted to flashing using microcode.
Also I don't understand why this e72aca9 ? because this stop currently running program in MCU but don't restart all the peripherals and it make many problems. reset_halt is not halt under reset but reset and halt on first address..

I'm running OS X 10.11 with an eBay ST-Link v2 connected with a WiFiMCU/EMW3165.

I am looking for a linux compatible tool to flash n76e003. If necessary, I would also invest some time to build one using Python. Any known attempts using pystlink to do the same? Would pystlink be a good starting point for that?

running on stm32l151zDT6:
sudo python3 pystlink.py -d

I get similar results with the stlink v3

I am making a connection with python using pyserial with a UART port. As I send the command using serial.write my output is received but my serial port does not break connection. As I need to send a second command also to receive the output. Please guide me on this.

I have also used ser.close still I am not able to close the port.

import serial

ser = serial.Serial(
port='COM5',
baudrate=9600,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS,
timeout= 10)
print("connected to: " + ser.portstr)

ser.write(b'\reeprom\r')
seq = []
count = 1

while True:
for c in ser.readline():
seq.append(chr(c)) # convert from ANSII
joined_seq = ''.join(str(v) for v in seq) # Make a string from array

        if chr(c) == '\n':
            print("Line " + str(count) + ': ' + joined_seq)
            seq = []
            count += 1
            break

ser.close()

Can you please guide what is going wrong. I am expecting that I should get my output of the fired command to UART and then code should exit rather than continue running. Also I wanted to know if this works can I again make connection and fire the second command to UART. Please help me on this.

@desprit - I have take this cutting of code from your stack overflow contribution. Can you help me guide what is wrong at my end that i am not able to release port.

As title,when I use flash erase command on STM32H745, it deosn't work as all

Hi! I am able to successfully load firmware in NUCLEO-F103RB if the NUCLEO is no modified, with its own STLINK connected internally via PCB and supplied by USB. However, when y cut ST-LINKV2 of NUCLEO and connect Externally via SWD connector, and supplied MCU externally I get Low supply voltage message:

 $pystlink.py -c STM32F103xB flash:erase:verify:F103_PruebaLED.bin
 
 DEVICE: ST-Link/V2-1 V2J40M27
 SUPPLY: 0.01V
 CORE:   CortexM3
 MCU:    STM32F103xB
 FLASH:  128KB
 SRAM:   20KB
 Loaded 5924 Bytes from F103_PruebaLED.bin file
 *** Supply voltage is 0.01V, but minimum for FLASH program or erase is 2.0V ***

Pin connection:

That connection works with STM32CubeIDE for programming MCU successfully (I think pin 6 is unnecessary).
I dont know if pin 1 is necessary.

In order to test, I tried skiping MCU voltage verification commenting this two lines:

# if self._stlink.target_voltage < 2.0:
     # raise lib.stlinkex.StlinkException('Supply voltage is %.2fV, but minimum for FLASH program or erase is 2.0V' % self._stlink.target_voltage) 

It works properly! It loads the firmware successfully.
So, I want to know if there is a way to solve this issue without skipping verification.

Thanks for all!
