AM263P4: Uniflash UART Fails to Flash Appimage Larger Than 1MB on TMDSCNCD263P EVM

Part Number: AM263P4
Other Parts Discussed in Thread: UNIFLASH, TMDSCNCD263P

Tool/software:

Hello TI Team,

I’m encountering an issue with Uniflash UART on the TMDSCNCD263P EVM. When flashing an appimage larger than approximately 1MB using the Uniflash GUI, the process fails. However, smaller images (under ~1MB) flash successfully.

Interestingly, when I use the command-line tool (python uart_uniflash.py -p COMxx --cfg=uart_uniflash.cfg) with the same appimage (around 1.1MB), it works without any issues. This suggests the problem may be specific to the Uniflash GUI application, although I cannot confirm this with certainty.

Could you please investigate this behavior? We would prefer to use the Uniflash GUI in our project due to its convenience.

Thank you for your support.

Regards,
Moonil

    Hi Moonil,

    What version of the UniFlash and the SDK are you using? I believe this should be resolved in the latest UniFlash versions.

    Hi Shunak,

    • Uniflash Version: 9.2.0.5300
    • SDK version: mcu_plus_sdk_am263px_10_02_00_15

    Please let me the exact version I have to use to resolve this issue. Please don't say just the latest version in our communication.

    To avoid suggesting something that has already been applied but proven ineffective, I'm sharing a portion of the script in v9.2.0

    Regards,

    Moonil
