Flashing multiple DLPC350 via JTAG

Richard Natho

Part Number: DLPC350

Hello,

I was wondering whether it is possible to automatically flash multiple DLPCs via JTAG. I have managed to daisy-chain the DLPCs to one UM232H and all DLPCs are found in the device chain. However, I can still only flash one device at a time. Is there a way to automatically flash all devices in the connected chain?

Thanks in advance

Hello Richard,

Welcome to the E2E forum and thank you for your interest in DLP® technology!

Can you say what board is being used in this case? Is this a custom board or an EVM?

Regards,

Austin

Hi,

we are using a custom board which is heavily based on the reference design. Until now our supplier for the PCBs with the DLPC flashed the firmware onto the boards. However, due to the fact that we we have to switch to a new supplier who is not that familiar with to DLPC we are currently looking for a good way to flash medium quantaties of DLPCs (about 100 boards per batch).

Beste Regards

Hello Richard,

We are considering your request to have this the JTAG target multiple flash devices at once. Please expect a reply from us by the end of the week.

Hi Richard,

Unfortunately we can not flash multiple targets detected at a time. You have to select the target number every time you need to flash.
