Other Parts Discussed in Thread: TDA2

Hi SIr

We used TDA2 for development and we change the DDR P/N and size (512MB).

Where should we modify about DDR timing setting and memory size setting ?

As we know , we should modify SBL first.

Do we need to modify other parts to let system can boot successfully and work well. ( for example : where to modify size for app image)

please advise

Hi,

You need to modify PROCESSOR_SDK_VISION_03_07_00_00\ti_components\drivers\pdk_01_10_03_07\packages\ti\boot\sbl_auto\sbl_utils\src\tda2xx\sbl_utils_tda2xx_ddr_config.c for DDR timing settings.

You don't need to modify app image and Vision SDK as 512 MB is supported by default.

Hi Sir

thanks for your reply.

Do you have any suggestion why it stopped in "Jumping to MPU CPU0 App" by using SDCARD/QSPI booting.

We have done the DDR test without issue.

Hi,

Is the DDR stable?

Can you check individual CPUs and see if any CPU has crashed.

What are the other changes that have made in SDK application?

Can you also try SBL mbx image from PROCESSOR_SDK_VISION_03_07_00_00\ti_components\drivers\pdk_01_10_03_07\packages\ti\boot\sbl_auto\prebuilt_binaries\sbl_multicore_mbx\tda2xx and see if it works.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Hi SIr

We have tried to load using CCS and it can work. The Menu can show up.

But it will hang at below message by using SDCARD booting.

Jumping to MPU CPU0 App

Do you have any suggestion

Hi Yimin,

Have you made any changes in the gel files when you got the custom board working?

If yes you should make sure that you have made same changes in SBL DDR configuration.

Also do you have any other changes in SDK?
