Part Number: DLPDLCR3310EVM
Tool/software:
Our company is currently experiencing abnormalities in the use of DLPDLCR3310EVM . We require official technical maintenance support or maintenance services from agents in the Chinese region. The specific symptoms are as follows:
We hope to change the boot interface, so we will use version 7.4 GUI software to update the firmware for EVM. The firmware have been downloaded on the TI website. After completing the update, there was a strange phenomenon with the product. We controlled the SW2 switch (from OFF to ON), and the indicator lights of D5 and D6 were able to switch normally, but the optical machine did not display any projected images. When I want to turn off the EVM, I switch the SW2 from ON to OFF, and the D5 and D6 indicator lights do not switch. I can only turn off the power by forcibly cutting off the power. After turning off the power, I attempted to re burn the firmware of the backup EVM itself to the system. After completing the update, the overall functionality and operating logic were restored to normal.We continue to try using GUI for firmware updates, but based on the official firmware provided, the above-mentioned issues are bound to occur. After multiple update operations, the system completely evolved into the above-mentioned phenomenon of being unable to operate. At this time, neither official firmware nor our own backup firmware archive can be restored. After investigation, there is no hardware damage, and it is preliminarily suspected that the unknown damage was caused by multiple updates.
Therefore, we hope to receive your company's support, clarify the causes of the problem and ways to avoid it, and also hope that your company can provide corresponding resources for repair services.
