This commit fixes an issue where the control block id was not found in cases where the bytes spanned two read blocks.
Example data block causing the original issue:
01:08:18.444,458] <dbg> SEGGER R
In this case the code skips 24 bytes, making the next loop start with:
SEGGER RTT\x00\x00\x00\x00…
Unfortunately
offset
is still8
, which the first byte does not match. The offset is then reset, but by that time the first byte has already been skipped over.Re: #1553
