Hi,
I made a PCB according to NIRscan EVM. Following this instruction http://www.ti.com/lit/ug/dlpu017a/dlpu017a.pdf , I am downloading the firmware.
In the first part with JTAGFlashProgrammer, it is OK, and it can erase and write 100%. Although it stuck somewhere, it can finally go to the end. I verified, there is no error.
But after it is re-powered, the DLPC350 cannot enumerates itself. Nothing shows up in computer when plugging the MIni-USB in J8, no matter J18 is installed or not.
DLPLCR4500GUI-3.0.1 is also disconnected.
I tried the firmware 2.0 and 3.0, it is the same.
Should the pin of V17(TRSTZ) be connected to ground or not when using the JTAGFlashProgrammer. It seems that it can always downloads in both.
And should J18 be installed or not when using the JTAGFlashProgrammer and after using JTAGFlashProgrammer.
Is there any specials with U11 USB2524?
So, Where is my problem?
Sorry I am not familiar with the booting procedure. I am really confused.
Thank you for you help!
