      couldn't get 3.4 to upload without CRC errors so even tried back peddling to 3.3. same issue. Upload the ZIP file , it decompresses than half way through I get CRC errors and the uploads stop. Have tried pulling down the files multiple times and retried the upload through the DWC still no dice.
      Any ideas? It fails on large AND smallish files. Currently on screen its a 495K file firmware/Duet2CombinedFirmware.bin that stopped it (rev 3.3 zip file) (setting up a brand new Mini 3 5+

        @ptegler i would try a different SD card. its usually the cause

        Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

          thanks @jay_s_uk ...figures...right after I posted I was able to resolve the issue. DNL'ed 3.3 and it uploaded as expected without issue. Then going back to 3.4 worked as expected without issue. Actually...the whole story...I expanded the zip first then uploaded the files en masse' so the DWC was not self unzipping the filed before upload. regardless I got past the CRC errors (finally)

            @ptegler I do hope that the filename you quoted (Duet2combined----) is a typo as surely a mini 3 5+ would need the duet3 firmware (Duet3Firmware_Mini5plus.uf2).
