RTC Clock Enabled Failed in uboot

Chad Graham1

Other Parts Discussed in Thread: AM3352

Hello,

I am currently trying to get uboot-spl file to complete execution on my board with an AM3352 and all clocks are enabling except for the 32k RTC. The specific debug output is:

Clock enable failed for 0x44e00800 idlest 0x10002

This is causing the code to stop execution at the rtc32k_enable function, while this clock fails to be enable earlier in the prcm_init().

Where should I look to fix this issue? Hardware looks fine from what we can tell.

Thanks

Hi,

Is it a custom board? Which version of the SDK/PSP are you using?

Best regards,
Miroslav

It is a custom board we designed. We are currently using EZSDK v 6.00

I have also compiled and ran the default u-boot settings from the SDK on our board and get the same error, if I run this same spl file on the EVM, it runs without error.

I believe that there is either a problem with the address of the RTC or a physical component error.

It would appear our RTC was not receiving power on the board.

We have resolved this issue.

Hello,

I'm a fresher working on AM3352 custom board and using ti-sdk-am335x-evm-07.00.00.00.

VRTC is proper with 1.8V.

Could you please help me. How it got resolved? Is there anything I have to look in.
