Other Parts Discussed in Thread: AM5749
Hello.
I have a TMDSIDK574 AM5749 board and would like to know about the DDR3 setup.
EMIF_RegisterConfig.xlsm (www.ti.com/.../sprac36)
was used to compare with the TMDSIDK574 set value.
EMIF_RegisterConfig
AM57x, DRA7x, and TDA2x Corrected items 13 and 14 according to the EMIF Tools guide.
The u-boot source used is the latest version of ti-processor-sdk-linux-am57xx-evm-06.03.00.106.
1. the values in the Register values (U-Boot) tab are different from the u-boot source contents. I want to know the reason.
