Hi,
Working DSS & Panel driver.
Sometime I am getting checksum error from DSI when framebuffers are
sent to panel via DSI.
omapdss DSI error: ACK with ERROR (0x400):
Wanted to know if some one has encounter similar error.
When / what can cause this error?
Regards,
Sudipta

Moi Tomi,
Have you ever encounter this error.
Looking some pointer what can cause checksum error.

Hi,
Most likely it is caused by electrical interference with the transfer.
Or, while very unlikely if it happens only rarely, a HW bug in the panel
(or even in OMAP).
