Hi Andreas,
Here are my findings. Thanks for the quick link.
As a sanity check, the same application with <1MB of flash size, still
works OK and all is happy, with the new 0.8.0-dev-00094-gc658229.
First thing you notice that the flash info reports a way much better
sectors layout, with the correct size of 0x00200000 (2048kbytes).
With the same application but >1MB, there is improvement but still not
loading properly with new errors. see below.
Notes:
- The MCU is not protected, i can reload the smaller app after these errors
and it will work OK again.
- The improvement is, it is trying to erase this time, compared to the
older v 0.7 .
- GDB error showing still: Error erasing flash with vFlashErase packet
- still using the 2 default config files (that comes with v0.8-dev):
target->stm32f4x_stlink.cfg and interface->stlink-v2.cfg
- I tried increase the work size to 0x20000 from 0x10000, stills same error.
Cheers,
