Are you sure there is no flash write protection?

[sawik-PL]

Just checked to be 100% sure. The sequence is following

$ st-flash erase
st-flash 1.5.1-28-gd040db5
2019-05-28T21:04:02 INFO common.c: Loading device parameters....

Mass erasing

Then flashing bootloader:

st-flash write build/STR-bootloader.bin 0x8000000
st-flash 1.5.1-28-gd040db5

Bootloader works
Then running

st-util -m -v

and trying to load app from eclipse/gdb

• works once
• doesn't work next times
• but works via command line "st-flash write build/STR-app.bin 0x8003000"

This wants verification with Release v1.6.0 and at least comparable hardware.

@Ant-ON: What is the actual definition of stlink_flash_loader_run(0x8003800)?

[Ant-ON]

@Nightwalker-87 I think this should be fixed by #1113
ps 0x8003800 is not an error code, it's the write address.

Closed by #1113.
