Hi guys, I tried to use a Serial Expansion HAT ( https://www.waveshare.com/wiki/Serial_Expansion_HAT ) on my BPI-M5. I must to use 5.17 kernel version (2022-04-09-raspios-bullseye-arm64-bpi-m5-m2pro-k5.17-sd-emmc.img) for my application, then I cannot change img.
If I enable I2C port and I check which device I have on I2C port (0 or 1) I cannot find my 0x48 device.
I did the same using a 4.9 kernel image (2022-05-25-raspios-bullseye-arm64-hdmi-edid-bpi-m5-m2pro-sd-emmc.img) and it works well. Someone have any idea to fix it? changing device-tree? Someone can help me? Thanks in advance.
