Tool/software:

Hi,

Customer modified TI demo with own alg and the code can work with CCS debug. But after they burned the image to flash, they found the code can't work ok. After connecting to R4F, they found the CPU is hanging in ROM.

Would you pls kindly advise what may cause hanging at 0x93E6? If you have any idea on how to debug this issue, pls also kindly share.

makefile_ccs_bootimage_gen：

SH_MEM_CONFIG=3

Thanks,

Chris

    Hey Chris,

    Could you ask them to check APP_CTRL:APPSS_BOOT_INFO_REG0 in the Registers or Memory Browser of the CCS debugger, and let us know what values are shown there during the ROM hang up. From there, we might be able to provide some additional debugging steps or information.

    Regards,

    Kristien,

    Pls find the info below.

    I tried with AWRL1432 engineering sample last time and now I got another xAWRL1432EVM. I tried to burn the same image and it hangs at different location in ROM.

    I mistake to burn the image on an AWRL6432 ES2.0 board and connected to CCS, I found the image didn't hang in ROM but stop at RAM instead of ROM. See the RBL boot is ok.

    For all tests, the APP_CTRL:APPSS_BOOT_INFO_REG0 value is same.

    Would you pls kindly advise any other suggestion?

    Thanks,

    Chris

    Hey Chris,

    Which version of the SDK was this image compiled with? Firmware support for xWRL1432 ES2.0 was only recently added to SDK 5.5 whereas xWRL6432 ES2.0 firmware has been supported since SDK 5.4. Please have the customer update to SDK 5.5 if they aren't using it already.

    Regards,

    Kristien
