Tool/software: Linux
Hi,
We are using PROCESSOR-SDK-AM57X ti-processor-sdk-linux-am57xx-evm-05.02.00.10, using UART1 (ttyO0) and customized am571x-idk. Device trees are modifile as per am571x-idk.
Booting through sd card by creating bootable sd card using this(tisdk-rootfs-image-am57xx-evm.tar.xz) tarball, having a problem with kernal booting it stops at starting kernal ......... for a long time and moves forward then regulator and ldo voltages are disabling. Please find the log below.
Kindlly suggest what's wrong.
