[FAQ] DLPC4422: How to repair the bootloader with UM232H.

Part Number: DLPC4422
Other Parts Discussed in Thread: DLP660TE,

Hi team,

Customer has some questions

I am using a DLP4422 with a DLP660TE. I mistakenly tried to upload an image to the DMD and it said to upload a flash image file and save on the bootloader, so now I can't get anything to work.

DLPC4422 is unable to communicate with PC, so I think I have a problem with the bootloader.

As linked above, it can be fixed using JTAG boundary scan on FTDI UM232H.
But I don't know how to use this module.

I would like to know how to load recovered files through UM232H.
Can I get a documentation about bootloader recover?


Best regards,
