hydrogenium2020 ce26824ed9 feat:SDRAM:bring up for 4GB DDR3L H5TC4G63AFR-RDA 792Mhz!
Here is the detail:
1. It has 2Ranks and 8bit*8.
2. There are some differences between H5TC4G63AFR-RDA and H5TC4G63AFR-PBA, and the parameters are not universal. If mixed use, it may lead to unstable data in memory writing (for example, data loss during writing).
