Need reference on where this limitation is captured.
Ref: https://www.ti.com/lit/er/sprz582a/sprz582a.pdf i2463 for AM62L
that this limitation is only for AM62L SR1.0 (But not on AM62L SR1.1)

Is there a Silicon or board errata doc specifically capturing this limitation ? Need references as well for all mentioned devices.

Considering AM62A release is with EdgeAI, will it be correct to mention boot support with 4GB & 8GB sized SD cards as the EdgeAI wic image size (tisdk-edgeai-image-am62a-evm-11.01.07.05.rootfs.wic.xz) is ~11 GB in itself - https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-AM62A/11.01.07.05 ?
