WeACT 8MB Blackpill, mpremote mip install corruption?

[davefes]

Edit title to : WeACT 8MB BlackPill possible SPI FLASH corruption.

On brand-new WeACT Blackpill 8MB boards I can load this firmware:

https://github.com/nspsck/STM32F411CEU6_BlackPill_Micropython/tree/main/firmware/WEACTF411CE8MB

change the filesystem to LFS2 and load up some test files using rshell on a Linux box. All
appears to be good.

I then mpremote mip install lora-sync and lora-sx127x. These end up in /lib/lora

But when I unplug the board and plug it back in there are no files in /flash. Also, if I try to use rshell to copy some
test files I get the dreaded:
timed out or error in transfer to remote: b' ' error.

As well as the error if I try to re-connect the process stalls at:
Retrieving sysname ... pyboard for 5-10 seconds, but then appears to complete ...
although I have to hit enter to display /flash

Has anybody had this problem with new WeACT 8MB boards?

Using mpremote appears to resolve this problem.
