Hello,
I manage to work with new S310 V2. I use S310 for hrm only. Saying so also not for DFU service. I have own proprietary method for transfering application images via serial port using bootloader.
Now I want to replace the Softdevice. a) Which commands do I have to issue? probably :
- remove write protection for memory from SD vector table start (0x1000) upwards until App vector table start
- SD_MBR_COMMAND_COPY_SD
- ...
- establish write protection b) How does the MBR checks a propper, valid SD? c) What will the MBR do on reboot when the SD update failed?
Regards, Adib
