I have a custom H7 plus board which already had working but changed flash and sdram to different PN in theory compatible. W25Q256JVEIQ and IS42S32800J-6TL.
I manage to load the firmware however when I plug in the Openmv I hear the device USB device enumerate, quickly see the USB symbol on the connect button and then it disappears. LED flashes blue at a high frequency I guess 10 Hz. Not slow blinking blue as usual when openmv is on waiting for connection.
Does anybody know what flash blinking blue means so I can debug?
