I've just finished my testing. I verified these results on two separate Gen 2 CMM2's (with separate SD cards) - and they did the same things.
I also tried doing a "full chip erase" before writing from STM32Cube and that didn't help.
I have the "Verify after programming" option checked.
With the original firmware 5.07.01.bin the corrupted video effect does not happen.
With the first firmware you posted on this thread, the video corruption effect does not occur.
With the second firmware you posted on this thread, the video corruption does occur.
I have toggled back and forth between original firmware and latest a few times on the two machines and the results are consistent.
The test program I am using is below, and the issue appears to occur when I load an image. I tried both JPEG and PNG and both exhibit the same problem.
The corruption is random though. If I put the LOAD JPG within the DO-LOOP, then the location and colours of the corrupted image change with each loop.
'MODE 1,16 ' 800x600
PAGE WRITE 1
LOAD JPG "img\crt3.jpg"
PAGE DISPLAY 1
DO:LOOP
The is the crt3.jpg file I am using
crt3.zip
And this is an example of what it looks like when loaded by the new firmware
To be clear, the old firmware still works 100% fine, so I am very very happy to carry on using that. I just thought this info might help.
