Hi all,
I have a problem with reading from RAM whet I set aligment to 1 byte. Strange
is that reading in 4-bytes aligment is OK.
My setup is:
Open On-Chip Debugger 0.10.0+dev-00957-g9de7d9c8 (2019-11-15-13:16)
stlink-3
stm32g431
I'm using openocd as lib.
~~~
// this is ok
res = api->read_mem(handle, RAM_START, 4, ramKb * 0x100, buf);
// here we fail (-7)
res = api->read_mem(handle, RAM_START, 1, ramKb * 0x100, buf);
~~~
and log:
