Hi TI
There's a question that Customer wants to clarify.
They consider to change LPDDR4 memory for their custom board. TDA4VM' EVM uses MT53D1024M32D4DT(32Gb), But they will use MT53D512M32D4DT(16Gb).
Could you please let us know how to modify dtsi and relevant code in PROCESSOR-SDK-Linux_7.3 ?
We have DDR Config Tool written in Excel. But not experienced.
Hence we need your kind support with detailed steps.
Thanks.
Regards,
Jack
Hi Kevin
There're unclear things about Frequency Set 0-2. and For Frequency Set 1, It's locked which can not be modified if other memory does not support 1866 MHz. Actually We tried to consider with SK Hynix. memory at first. It has slightly different parameters regarding clock rate and so on. Customer still compare Micron 16Gb vs SK Hynix 16 Gb through other E2E ticket since They will reduce DDR size from 32Gb to 16Gb.
We found a document which describes compatibility btw Sitara and Micron device.
The exact part will be MT53D512M32D2DS-053-AUT as you found.

Hi Jack,
I am not sure what is unclear about Frequency set 0 - 2. As mentioned on your other thread below, frequency set 1 is locked for a reason and will auto adjust when you configure frequency set 2. This is also stated in the tool itself.
