Just to confirm, after the first time that bootloader, partitions, and boot_app0 bins are burned they don't seem to require reflashing. Since I'm making small changes to the code, I can just update the main bin file: esptool.py --chip esp32 --port /dev/serial0 -b 460800 write_flash -z --flash_mode d...

Well, looks like I was missing 0xe000 boot_app0.bin in the command to burn the firmware, which seems to have been fixed. esptool.py --chip esp32 --port /dev/serial0 -b 460800 write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 $1.ino.bootloader.bin 0x8000 $1.ino.partitions.bi...

Thank you for your reply. When Arduino compiles it gives me a partition.cvs as well, here is the output in this case: # Name Type SubType Offset Size nvs data nvs 0x9000 0x5000 otadata data ota 0xe000 0x2000 app0 app ota_0 0x10000 0x140000 app1 app ota_1 0x150000 0x140000 spiffs data spiffs 0x290000...

I'm on my first design using this ESP32, but I'm having trouble to make it work. On the hardware side, I used the reference existing in the ESP32-Pico-V3 Datasheet, just connecting the IOs that I needed. In any case, the circuit is the following: http://avti.com.br/ESP32-Pico-V3.png I'm using a Rasp...
