工具与软件:
您好、先生/女士:
我们的代码库是 ti-processor-sdk-linux-edgeai-am62a-evm-10_00_00_08
根据我们的硬件设计(与 EVM 板类似)、我们使用 sdcard 启动。
遵循 SK-AM62P-LP:如何将 SD 卡设置为仅3.3V (低速) 以禁用高速模式。
我们还禁用第二个未使用的 CPU。
但在启动时、我们会被困在内核中、来显示以下内容:
[ 12.037450] mmc0: CQHCI version 5.10 [ 12.080971] mmc0: SDHCI controller on fa10000.mmc [fa10000.mmc] using ADMA 64-bit [ 12.262364] mmc0: Failed to initialize a non-removable card [ 12.329280] pca953x 1-0022: supply vcc not found, using dummy regulator [ 12.341668] pca953x 1-0022: using AI [ 12.345431] pca953x 1-0022: failed writing register [ 12.350478] pca953x: probe of 1-0022 failed with error -121 [ 12.360986] debugfs: Directory 'pd:182' with parent 'pm_genpd' already present!

在 uboot 中、我们更新 SD 卡低速变化和 DDR 配置设置。
在内核中、我们将更新 SD 卡低速并禁用第二个 CPU。
以下是我们的更改和日志、您能帮助检查为什么会出现此类错误吗?
谢谢。
