您好!
我无法成功执行 AM243x MCU+ SDK:EVM 设置指南中的"Flash SOC 初始化二进制文件"步骤:
https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_06_00_43/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html
我能够设置串行终端并接收"C"字符、这表示电路板处于"UART 引导"模式。 但是、当我运行 python 脚本时、我会收到以下错误:
PS C:\ti\mcu_plus_sdk_am243x_08_06_00_43\tools\boot> python uart_uniflash.py -p COM3 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg Parsing config file ... Parsing config file ... SUCCESS.

我还使用 AM243x-EVM 和 AM64x-EVM 尝试了相同的步骤、对于每个电路板、我会得到相同的错误。 此外,我尝试了两台单独的计算机,并收到了相同的错误消息。
AM243x IC 上的标记为"XAM2434B" 这是否表示器件是 HS FS、而不是 GP? 这是否需要额外的设置步骤?
您对闪存设置有什么建议吗?
