DLPNIRNANOEVM: Scan Error:DLPC150 Boot error detected

Hi Chiu,

Welcome to the TI E2E forums and thanks for showing interest in the DLP technology.

We will look into the issue you reported and get back to you soon.

Thank you!

Thank you for your attention.

We can provide the snapshot and videos, please let me know if it will help. 

Warm regards

Hi Chiu,

What does the error message show in DLP NIRscan Nano GUI?

It would be help if you could provide the snapshots. 

Thanks!

Lori

Here are the information we could collect so far, there is nothing further we can do. 

Please advise the next move.

Hi Chiu,

Thanks for sharing the snapshots. 

While updating the DLPR150PROM_2.3.1.img using DLP NIRScan Nano GUI v2.1.0, there is no image validation check being done as of now.

Hence, if  the DLPR150PROM_2.3.1.img is corrupted then you would be getting the DLPC150 Boot error detected message. This might happen while extracting the firmware installation tool or if the image file is being edited.

So, Could you please try downloading the DLPC150 V2.3.1 firmware again and ensure there aren't any warning or errors while extracting.

Regards,

Akhil

Dear Akhil, 

I'd downloaded firware installer and extracted DLPR150PROM_2.3.1.img again accord to your advise. 

However, after reboot, the same error message still shown as attached snapshot. 

The latest extracted DLPR150PROM_2.3.1.img shown as 179,384 bit. Not sure if it could help to verify the img file is a none-corrupted by file size like this. 

Please recommend the next step. 

Cheers

Hi Chiu,

Apologies on the delay. We are currently discussing about this internally and will get back to you with further insights ASAP.

Just in case, Can you try updating the firmware of the Tiva controller and check it once in the mean time.

Akhil

Dear Akhil, 

I'd redownloaded DLPNIRscanNanoSoftware_2.1.0 and flash it again. Just in case if the bin file discrepancy happens, the file size we are flashing is 377,168bit for your reference. 

Hi Chiu,

Thanks a lot for the confirmation. We will get back to you ASAP.

Akhil

Hi Akhil, 

Hi Akhil, 

Hi Akhil, 

May I ask if there is any further action we can do from here?

(sorry for duplicated reply, I have no idea how it comes, please ignore the other message)

Chiu,

When did this issue start happening? Has this been a problem since you purchased the EVM? If so, perhaps there is a problem with the EEPROM flash device on the board. Any details you can share on the same?

Regards,

Philippe

Dear Philippe, 
Thank you for following up. 
We found the scan issue at the first day we open the box, and we raise the TI tech support at the 2nd day.(3rd August)
We didn't have a chance to evaluate does the spectrum was correct or not, then scan failed warning kept happen after the DLPC and Tiva FW update. We'd tried to flash both version back but it wasn't help to recover the DLPC connection problem. We ever able push the scan button successfully (without any sample at the front of window) at the beginning. But we are pretty sure the connection problem was happened after the FW update. 

Hope this information helps, please advise the next step.

Thanks

Samuel
