LP-AM243: UNIFLASH tool qspi flash

Alexander Hänel-Baas

Part Number: LP-AM243
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hi,

I have a question about the UNIFLASH tool.

We're using the launchpad board, and I'm using the guide

AM243x MCU+ SDK: Flashing Tools

as a template for flashing the application.

I have changed the config file to my needs, and I can use successfully the python command:

python uart_uniflash.py -p {name of your UART com port} --cfg={path to your edited config file}

After the board is switched from UART_BOOT_MODE to QSPI_BOOT, the application starts successfully.

I now want to use the TI Uniflash tool. The board is scanned, but flashing in UART_BOOT_MODE is not possible.

What am I doing wrong?

Best regards

Alexander

    Hi,

    If the flashing is already done, then what do you need the UNIFLASH tool for?

    If you have already flashed via the python uart uniflash command, then there would be no further use of UART Uniflash tool, as the UART Uniflash tool serves an alternate to flashing via the commands.

    Hi Vaibhav,

    that's right from a technical point of view.

    We are currently evaluating the use of the Sitata AM243 in our company.

    In development, the developer is welcome to flash the board via python script. No problem.

    This is not usable in production. Here is the use of the graphical flash tool a basic requirement.

    So it is necessary for me to get this tool working.

    Greetings

    Hi,

    I am trying to flash this on the AM243-LP TI EVM and will update in sometime when I have further steps to talk about.

    Hi,

    I have been able to successfully flash via the Tool on AM243-LP TI EVM.

    I followed the following steps:

    1. From the dropdown options I selected the AM243 Serial option in order to facilitate flashing via UART.
    2. Post this we move forward to the following screen where we need to choose the correct COM Port number, in my case it is COM8 and then since I am working with AM243-LP I went ahead and selected the LP option out of the two options available.

    Post this, I simply upload the SBL image, the application image and the XIP image and the flashing is seen to be successful.

    Hope the above steps help.

    Regards,

    Vaibhav

    Hallo Vaihav,

    Thanks for testing.

    After I manually switched the connection to serial, it works.

    Do you have any idea why auto detect doesn't work?

    Regards,

    It is because, the autodetect just rightly selects the SoC/TI EVM and then in the next step which is where we choose device under New Configuration, we need to correctly select how we want to flash the data, either via JTAG or the Serial option.

    Hope this helps you out.

    Marking the thread closed.
