Please use the DSI86 spreadsheet I sent you in the private message to generate the values for the DSI86 registers.

I would also suggest getting the color bar working first as part of the debug.

Thanks

David

The panel may not support ASSR.

In this case, please have TEST2 pin pulled high, and then run the script that disables the ASSR.

======ASSR RW control ======
<i2c_write addr=0x2D count=1 radix=16> FF 7 </i2c_write>/>
<i2c_write addr=0x2D count=1 radix=16> 16 1 </i2c_write>/>
<i2c_write addr=0x2D count=1 radix=16> FF 0 </i2c_write>/>

Please also dump out register 0xF0 - 0xF8 when there is no color bar.

Thanks

David
