Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Last night I was playing with an old handheld with a 2350 and an ili9341. Thought I would update the firmware to the newest. It would not boot up? Tried several times with wiping out the device and re-loading. Ok, wondered if there was a problem with just that file. Downloaded it again. Still no go. Started going backward in versions till I could find one that worked. Had to go to version 6.00 to get it to boot. Strange. Went back to the newest and again , no boot? Could there be a problem with just that one file with no usb and no video? I have the newest file working on an HDMI version just fine.
Puzzled......

All were PicoMiteRP2350Vxxxx , the only one meant for no video and no USB keyboard.

All the VGA and HDMI versions I have tried work just fine. I don't use the WEB version ones , at least not yet.

I've just been bug fixing using what is now PicoMiteRP2350V6.02.00RC2.uf2 and it works absolutely perfectly on a standard Pico2. What H/W are you using? Clear the flash completely using the clear_flash.uf2 in the download and then install RC2

Ok , I found that version , tried it and success!  Went back and re-tried 5 other versions and no go. I have the new one loaded and running so thank you very much. It was a SeeedStudio board , the short one.
