Part Number: AM3352

Hi,

Our EMIF values (attached) could only successfully bootup 1 out of 10 boards in the PCBA batch.

Any software values we should tune further or anything in the layout we need to improve?

Your help is greatly appreciated!

Anik, can you send the DDR part number that you are using? Also, what software are you using to initialize the memory? If you have JTAG access, please run the following script after initializing the memory: https://git.ti.com/cgit/sitara-dss-files/am335x-dss-files/tree/

am335x-ddr-analysis.dss

REad the README file for instructions on how to run the dss file in CCS, and post the results here

Regards,

James
