[Question]DMT48270C043_06WT - white screen after update

pmc

Tried to update this using SD card but ended up with a white screen. It now seems that there is no attempt by the display to access the SD card (no activity on the SD card pins can be seen on an oscilloscope). The unit does not respond to commands on uart 2 pins at 115200 baud. I have tried the clock recalibration procedure given in a document in the forum but nothing works.
