TDA4VM: SBL start up error and halting in DDR init progress

yang he

Part Number: TDA4VM

Our board can run normal by SPL ,but can not be started by SBL.

We find the MCU sbl code is halting in ddr init progress,the DDR is from company SK Hynix Memory,Part Number is H54G56BYYPX046.

Our SDK version is 7.2,and BOOT mode is MMCSD.

Can you give us some advice?

Thanks!

Hi,

Assuming this is all on a customer board. Did you need to make any changes to run SPL/u-boot from SDK7.2 on your custom board?

Hi Team:

We provided latest memory parameter and test at customer board. New parameter can work at 4266 MT/s speed.

This problem resolved.

Best Regards!
