Erasing and programming the chip with the command:

sudo st-flash --freq=4M  erase  0x8000000 0x100000 | sed 's/\r/\n/g'
sudo st-flash --freq=4M --debug write ./cmake_build/HMC20/develop/GCC_ARM/hmc20_test.bin 0x8000000

Gives as output result:

The last two in32's are not correctly written. If I program the same bin file with the STM32CubeProgrammer, I can see the difference:

Flash ST-Link
Flash_StLink

Flash CubeProgrammer
Flash_CubeProgrammer

I wrote a Python script as a workaround:

#!/usr/bin/python

# Python 3.10.12

import os, sys

file = ''
bytes = 0

if len(sys.argv) < 2:
    print('Give file name as first argument')
    exit(1)

file = sys.argv[1]

def append():
    try:
        with open(file, 'ab') as bf:
            print('Appending 0xFFFF to file ' + file)
            bf.write(b'\xFF\xFF\xFF\xFF')
    except OSError as e:
        print(e)
        exit(1)

def main():

    if not os.path.exists(file):
        print('File ' + file + ' does not extsis')
        exit(1)
  
    bytes = os.path.getsize(file)
    print('File size: ' + str(bytes) + 'bytes')

    if (bytes%4):
        print('File not multiple of 4 bytes')
        exit(1)
    
    ds = bytes/4

    if (ds%4 == 1):
        append()
        append()
        exit(0)

    if (ds%4 == 2):
        append()
        exit(0)

    print('Nothing to append')
    exit(0)

if __name__ == "__main__":
    main()

@lefebvresam Thanks for reporting and analysing the issue which seems to be an issue with alignment.
However I've no idea yet on how to address this appropriately in the codebase...

@Nightwalker-87 U5 chips request 16 byte alignment for write. I think need add alignment before line
DLOG("Starting %3u page write\n", len / sl->flash_pgsz);

Alignment:

    if (sl->flash_type == STM32_FLASH_TYPE_L5_U5_H5 && (len % 16))
    {
        WLOG("Data size is aligned to 16 byte");
        len += 16 - len%16;
    }

@Ant-ON I'll give it a try. I do have a Nucleo U575ZI-Q board at hand and may likely be able to reproduce and test.

@lefebvresam I was able to reproduce your setup with a Nucleo U575ZI-Q board.
The proposed patch by @Ant-ON fixes the problem, as can be seen above.
This test used the first mem.bin file as described in #1362 (comment).
I'll submit the patch to the testing branch for further verification.

I pulled the testing branch, installed again and it seems to work now. I'll no longer need my Python script. Thanks.
