We have 1MB flash memory available can we use it to support OTA. We are receving updated binary through BLE and storing it to SD card using Arduino sketch at moment.
Can we use some Arduino Sketch to store this binary directly into flash/program memory. In bootloader we just change entry pointer to point to new downloaded firmware. new binary available or not can be indicated throguh EEPROM status flag.
This is beyond what Technical Support is prepared to provide, but we will leave this topic open in case someone with hardware engineering experience has some useful input to provide.
It might be best to determine this experimentally by trial-and-error.
Fascinating approach to storing/updating binary- I’ve been interested in this approach- our group is researching porting linux (a very light one) to the Apollo3: https://forum.ei2030.org/t/research-por … ller/151/2
