TDA4VM: UNIFLASH 6.1.0 segment fault on Linux machine

Part Number: TDA4VM
Other Parts Discussed in Thread: UNIFLASH,

Dear experts,

When I tested with UNIFLASH 6.1.0 on Ubuntu 18.04 host with TDA4VM EVM, I got segment fault. Is there a known issue?

I tested Windows UNIFLASH 6.1.0 it works fine. I tried minicom and got "CCCCC" in the serial port.

~/ti/uniflash_6.0.0$ ./dslite.sh --mode processors -c /dev/ttyUSB1 -f ./processors/FlashWriter/j721e_evm/uart_j721e_evm_flash_programmer_release.tiimage -i 0
Executing the following command:
> ./ProcessorSDKSerialFlash -c /dev/ttyUSB1 -f ./processors/FlashWriter/j721e_evm/uart_j721e_evm_flash_programmer_release.tiimage -i 0

For more details and examples, please refer to the UniFlash Quick Start guide.

    Hi ZM,

    The issue is that you are giving the relative path to the image in the command you are using. I tried the same and got the segmentation fault myself.

    Replace the relative path by absolute path (~/ti/uniflash_6.0.0/processors/FlashWriter/j721e_evm/uart_j721e_evm_flash_programmer_release.tiimage) and you should be able to flash.

    Use the below command:

    ~/ti/uniflash_6.0.0$ ./dslite.sh --mode processors -c /dev/ttyUSB1 -f ~/ti/uniflash_6.0.0/processors/FlashWriter/j721e_evm/uart_j721e_evm_flash_programmer_release.tiimage -i 0

    Regards,

    Karan
