AM2732: 使用python uart_uniflash.py烧录无反应

Part Number: AM2732
Other Parts Discussed in Thread: UNIFLASH, TIDA-020047

hi,

我使用python uart_uniflash.py烧录我们自己打样的TIDA-020047板子,烧录失败,监测串口数据,无数据下发,如下图,请问是什么原因?

  • python uart_uniflash.py -p COM22 --cfg=sbl_prebuilt\am273x-evm\default_sbl_qspi.cfg

    Parsing config file ...
    Parsing config file ... SUCCESS. Found 3 command(s) !!!

    Executing command 1 of 3 ...
    Found flash writer ... sending sbl_prebuilt/am273x-evm/sbl_uart_uniflash.release.tiimage
    Sending sbl_prebuilt/am273x-evm/sbl_uart_uniflash.release.tiimage: 0%| | 0/53542 [00:00<?, ?bytes/s]

  • python版本号:

    C:\ti\mmwave_mcuplus_sdk_04_04_00_01\mcu_plus_sdk_am273x_08_05_00_24\tools\boot>python --version
    Python 3.7.3

  • 在上电之后,我在串口调试助手里面  看不到 字符 “C”  

  • 请问您的板子和TIDA-020047一模一样吗?同样的操作在TIDA-020047可以吗?

  • 模块问题,换个模块就行了

  •  第一个指令正常了,第二个指令 无响应,是什么情况呢?

  • 你好,是用的TIDA-020047的打板资料做的板子,PMIC电源还没有输出,调了半个月了,现在是外部给各路电源供电来调的。

  • cfg文件如下:

    #-----------------------------------------------------------------------------#
    # #
    # DEFAULT CONFIGURATION FILE TO BE USED WITH THE FLASHWRITER SCRIPT #
    # #
    #-----------------------------------------------------------------------------#
    #
    # By default this config file,
    # - points to pre-built flash writer, bootloader for this EVM
    # - The application image points to relative path of the ipc echo application image for this EVM
    # - Make sure this application is built before running this script
    # - You can customized this config file to point to your own bootloader and/or application images
    # - You can use --operation=flashverify if you just want to verify the flash contents and not flash the file.
    #

    # First point to sbl_uart_uniflash binary, which function's as a server to flash one or more files
    --flash-writer=sbl_prebuilt/am273x-evm/sbl_uart_uniflash.release.tiimage

    # Now send one or more files to flash or flashverify as needed. The order of sending files does not matter

    # When sending bootloader make sure to flash at offset 0x0. ROM expects bootloader at offset 0x0
    --file=sbl_prebuilt/am273x-evm/sbl_qspi.release.tiimage --operation=flash --flash-offset=0x0

    # send the application image to flash. Flash it at 0xA0000 as the SBL expects it at this location
    --file=sbl_prebuilt/am273x-evm/empty_system.appimage --operation=flash --flash-offset=0xA0000

    建议先检查一下板子硬件问题,PMIC电源的输出问题先解决一下。

  • 外部供电,可以烧录第一个文件了呀,为什么第二个文件烧录不了呢?可能会在哪些地方存在问题?

  • 可以先在TIDA-020047操作一下,同样的代码,同样的操作步骤如果在EVM板上可以的话,那就可能是板子的硬件问题了。
