请注意您的友好关注。 感谢您的支持。

从中删除 MMCSD/eMMC 实例后、UART uniflash 命令流程会正常工作  example.syscfg as we are using only OSPI and no DDR or MMC on custom board.

OSPI Daignostics says all tests passed 

但是、在尝试使用 Uniflash GUI 与配置的 XDS200 进行连接时、我们会收到以下错误:

Run failed... File Loader: Memory write failed: Timed out waiting for target to halt while executing am243x_alv_flasher.out

 

 

另外,当我们连接到 UART 终端并按重置时,我们会连续接收 "CCCC" 而不是引导 sbl_null

您能否建议在 Uniflash GUI 模式下导致此问题的原因?
