Tool/software:
Hello,
i have programmed a custom bootloader app (start flash address 0x80000) <=> for that i have programmed OTP via DCSM (5.4.3.1 Zero Boot Mode Select Pins) and startaddress 0x80000.
Memory dump:
0x78008: FF FF 1F 03 FF FF FF FF 7F FF FF FF FF FF FF
In the bootloader application i read a defined memory area where i store update data <=> which application is active app1 or app2.
After that i set the entryaddress to 0x88000 or 0xA8000 and then do the codeline "((void (*)(void))entryAddressApp)();
Software actual app1/2: init => spi sd card write logging => swtich active app => end
Test debugger bootloader app:
start debugger bootloader app => read stored data (active app1) => start app1 0x88000 => change active app to app2 in the stored data (via Fapi) (end)
start debugger bootloader app => read stored data (active app2) => start ap2p 0xA8000 => change active app to app1 in the stored data (via Fapi) (end)
Test without debugger. Power on hardware => app1 start => power off => power on => app1 start
Any help?
Bset regards Daniel
