Hello.
I'm trying to load some image file to FLASH with 'uart_uniflash.py' script and has some errors.
When flash offset is set multiple to 0x20000 (for example 0x80000, 0xA0000, 0xC0000) it returns "[STATUS] SUCCESS !!!", otherwise (for offsets 0x81000, 0x90000, 0xA0800 and so on) it returns "[STATUS] ERROR: Flashing failed !!!"
I assume, that reason is loading data to flash by blocks. But is it limitations of bootloader, which can be avoided by using custom one, or hardware limitation of used on-board flash?
Config file used in script is very simple:
--flash-writer=sbl_uart_uniflash.debug.tiimage --file=<some image file> --operation=flash --flash-offset=0x90000
Results with offset 0x90000

Results with offset 0xA0000 (the same for 0x80000, which is actual for further SBL work)
