Hello,
I’m trying to use a MIPI DSI display of mine, but I’m having trouble finding where to edit and send the MIPI timing parameters. can any one help me to make mipi dsi interface working. i have EDGE-V V13 board and using android 9 sdk.
Thanks
Hi @goenjoy
I have followed step mentioned in the document, but our custom display supports only Non-Burst mode video operation with Sync Events and the continuous clock on clock lane.
so for this in the device tree, I need to provide in “dsi,flags” to generate sync Events and the continuous clock on clock lane. so what i have to set in dsi,flags in device tree can you help me to set this flags and generate clock on mipi clock lane.
Thanks
Thanks, @goenjoy for the reply.
I am getting below error while setting the clock frequency provided by the display vendor. can you please help me out to resolve this.
Error :
dw-mipi-dsi ff960000.dsi: Host reports that the configured timeout counter for the high-speed
transmission has expired
dw-mipi-dsi ff960000.dsi: An overflow occurs in the DPI pixel payload FIFO
getting this error continuously. attached the screenshot of the booting log for the reference.
I don’t see any problems. First, make sure the hardware is OK. DTS configuration is OK. Then this screen can be displayed normally.
Do you know how to add Mipi DSI to Android 9 / 10 for this display?
This must be the main display and no hdmi or this display and the hdmi secondary display.

Will instructions here work ?
Hi, I see here - Edge-V w/ Dual Independent Displays (HDMI + MIPI-DSI + TP)
It is for another user I help so I can’t test it myself, so just want to make sure of the exact changes needed.
@mo123 As long as the Mipi interface corresponds to OK, the parameter adjustment will be able to light up.
