Fix "Can't find mipi_dsi_host!" error #89

Closed matsujirushi closed 4 months ago

matsujirushi commented 5 months ago

https://github.com/Seeed-Studio/seeed-linux-dtoverlays/issues/28#issue-979865119

When reTerminal is powered off and powered back on, mipi LCD driver is not loaded. Need to do the following steps every time I turn on reTerminal

Fixed this issue.

dmesg log:
