Tool/software:
Hi, Sir:
Our codebase is ti-processor-sdk-linux-edgeai-am62a-evm-10_00_00_08
Based on our HW design (which is similar with EVM board), we use sdcard to boot up.
Following SK-AM62P-LP: How to Set SD Card to 3.3v only (low speed) to disable high speed mode.
And we also disable 2nd unused cpu.
But when booting up, we would get stuck in kernel to show below:
[ 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!

In uboot, we update sd-card low speed change and our ddr config settings.
In kernel, we update sd-card low speed, and disable 2nd cpu.
Here are our changes and logs, would you help check why we got this kind error?
Thanks.
