I can't start after setting led parameters

[zx804262156]

My panel is 32x32. I changed the parameter. The original parameter is 16. My panel parameter is 32, but it can't be started. It shows "flash read err, 1000". What should I do?

main.cpp
#ifndef PXMATRIX_ROW_PATTERN
#define PXMATRIX_ROW_PATTERN 32 // The row pattern for the display

From what I can tell, that error happens when it looks at 0x1000 for the bootloader and fails to find it. This project uses a custom flash partition layout, so that might be a factor. That parameter you changed isn't for the display resolution but for the inverse of the scan pattern, so the default 16 is for a 1/16 pattern. This is directly fed into the PxMatrix library, so I would first try one of the examples from https://github.com/2dom/PxMatrix to ensure you have the display working and the correct parameters before trying to get this project working. 32x32 panels typically have a 1/8 or 1/16 scan pattern, though.
