I'm using a raspberry Pi Pico for a personnal project (written in C language) and my problem is that my Pico is unreachable once it's installed so I have to take it out everytime I want to update my Software which takes forever. My pico is linked to a Raspberry Pi CM3 with a dedicated protocol ( that's not USB), I cannot add another wire for another protocol neither (USB or SWD). My CM3 is connected in Wifi, so far I can remotely send my update firmware to the pico, doing that I have my firmware stocked in a pointer in the pico (the firmware can be the .hex, .bin or .uf2 file).
My question is how can I use this pointer to reprogram my pico ?
On the pico SDK kit I have found out the functions flash_range_erase() and flash_range_program but it seems like its only to edit smalls part of memory and not the program itself. I know that I have to stop interrupts in order to do that and to stop my second core to avoid problems. I also found the function reset_usb_boot() that allows me to reboot on boot USB mode without having to press the Bootsel button which is realy convenient. The problem I have is that once in this mode, I cannot use my pointer containing the firmware because I juste rebooted my Pico and I cannot send the firmware that the pico is waiting because I have no USB connection to it.
I would like to know if there is any way of programmatically reflashing the Pico.
Thanks in advance for your help.
