Hello team,
I have designed a custom board using AM3358.
In one of the boards I have found that processor is not booting.I have checked the UART log and even CCCCC.... was not coming.
So, I tried connecting the board using CCS(Code Composer Studio) and found the following error.
CortxA8: Output: **** AM3358_SK Initialization is in progress ..........
CortxA8: Output: **** AM335x ALL PLL Config for OPP == OPP100 is in progress .........

If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.4.0.00006)

If I try reconnecting again without power cycling , the board is connecting and processor is ready to boot and even I could see CCCC... on the UART log.
I could sense some voltage is not being properly ramped up and is causing issue. If i am sensing correct , Kindly help me in identifying the issue and solving it.
Else let me know what could be the issue.
Kindly reply at the earliest.
