Sometimes getting 521 error copying hex file to v2 microbit #5196

Closed eanders-ms closed 1 year ago

eanders-ms commented 1 year ago

When a microbit project contains v2 blocks, copying the downloaded hex to device will often result in a 521 error.

FAIL.TXT

error: The hex file cannot be decoded. Checksum calculation failure occurred.
type: transient, user

Interestingly, this only seems to happen if the project contains v2 blocks. With only v1 blocks present, the copy succeeds reliably.

I saved the hex files for these projects and tested dragging each to V2.21, and the V1 one to V1.5, ten times. The error rate was about the same in all cases (3, 2, 4 fails).
