Hi Experts,
I am asking for my customer here.
Customer using TI's Bootloader to do LFU/OTA, and customer jumps to the Boot from the APP and the chip cannot run normally.
1.Check Power supply, VDDIO/3v3 Normal,
2.Check PLL, Normal,
3.Check RPC and PC values when using JTAG without reset the CPU, check the RPC is 0x3FDC2B, the NMIFLG and NMISHDFLG is 0x0.
Do you have any comment here about "ExitPBISLoc"? Any suggestion/Dir? Thanks.
Hi Sira and Vamsi,
Another new situation update is as follows:
When we use JTAG to connect to the failed F280039 without resetting the CPU, we find that the GPIO and RAM registers have been cleared.
Could you help me to understand why the JTAG connect/emulator changes the status of the CPU under this issue? We can confirm that the XRSn Pin will not pull low when we connect the JTAG emulator. Thanks.
Hi Sira,
When we check the PC value and Load BOOTROM.symbol to the fault chip. The Code stuck at the below for(;;){}, unable to continue running.
Could you tell me about the LDRA_FILEIO? How to judge the Stuck position why the program runs to this line? Thanks a lot!
Hi Vivek,
Do you help to understand this following situation?
When we use JTAG to connect to the failed F280039 Target core without resetting the CPU, we find that the GPIO and RAM registers have been cleared. We have been testing that XRSn, VDDIO and VDD are all normal, and there is no reset or power failure. Under what conditions will this occur?
Even if we delete GEL files, the GPIO and RAM registers are still be cleared, Why not? Please help to look into this phenomenon.
