Hi, ti expert
Since the previous question had not been answered for a long time, I created a new one. Some related questions can be found in the previous question.
Links are "e2e.ti.com/.../3583390
I am using our costom board to boot from SD card. But it always shows "SRAM: identified size not same as expected size identified: 0 expected: 40000000".
Our costom board use two “MT41K256M16TW-107AATP” DDR. I follow the document "sprac36e.pdf", fill in some parameters in the "EMIF_RegisterConfig.xlsm" and update the value of register.
However, it still failed.
Can these situation cause the problem?
- I found that the CAS Latency for the parameter "EMIF_REGISTERCONFIG. CONF" is a maximum of 11. But our DDR CAS Latency has a value of 13.
- I fill nothing is the sheet "Step2-BoardDetails", because i think this is the hardware-related parameter.
The following "8360.EMIF_RegisterConfig.zip" shows the configuration.
