The development board for the Odyssey SOM board for Cortex-A7 STM32MP157C manages a MIPI-DSI interface
Using manufacturer supplied Debian version all works fine but the only driver dedicated to serial video is in the device tree: stm32mp1-seeed-lcd-01-overlay which is capable of handling only the tft orisetech otm8009a display.
the commands fbset -xres nnn accept a maximum horizontal resolution of 480 pixels.
if you want to use the raspberry 800x480 7 "display …
(although the first 15 pins of the connector are correctly wired), the display does not turn on.
Could it be due to the horizontal resolution being too low or the incorrect management of pins 16-20 of the Odyssey connector?
is it possible to modify the stm32mp1-seeed-lcd-01-overlay.dts to set a higher default resolution?
examining the source of the device panel-orisetech-otm8009a.c
there seems to be the possibility of changing the format (perhaps with a initialization message to display on lane 0 or via i2c?)
has anyone managed to interface the Odyssey card with a Rasperry 7 "DSI display or similar?
Thanks Best regards Livio Benvenuti
