Glad that worked for you !!!
That fix was applied to the master micropython branch.
it appears no maintenance is being performed.
lv_micropython has not appeared to be updated since 1-17-2020 !
I also get on boot…
a) flash read err, 100
b) Chip revision…
c) incorrect version 1.9.4 (1.12 is used)
Do not get the issues with pure micropython builds.
I currently also have have other problems.
Support is almost nonexistent as stated at the beginning of this thread…
Without a huge following, fixes are going to be non-existent unless one is very familiar with the code.
Me personally I might have to look for a commercial package as my project is not for fun.
Good luck.
