The RP2350 has a different blob header requirement to identify a working image. Ensure that header is present in the OTA loader. Update the PicoOTA examples for the 2350

// This example overwrites itself with a serial blinker sketch using OTA
|
|
// In general, you will get a file from the Internet, over a serial port, etc.
|
|
// and not include it in a header like we do here for simplicity.
|
|
//
|
|
// The blinker.BIN file was compressed with `gzip -9` and will be expanded
|
|
// during OTA
|
|
//
|
|
// You need to have at least 256K of filesystem configured in
|
|
// Tools->Flash Size
