Dear all,
We are developing a custom board based on the AM335x processor. Memory test through JTAG are ok, we modified u-boot to handle our DDR3 RAM Chip (2GB).
After some days of work, linux boot well and our device tree is ready.
However, I've a DDR memory size problem.
U-Boot says :
U-Boot 2014.07 (Feb 16 2015 - 15:35:23) I2C: ready DRAM: 256 MiB NAND: 0 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1
I don't understand why u-boot only see 256MB RAM instead of 2GB. I spent a lot of time by looking how and where is the ram size defined for the AM335x, without success. If I boot with my SD card on a beaglebone black, U-boot detect 512MB RAM.
So my question is, how to set the board RAM size and be able to use the whole memory !
Thank you in advance for your precious help !
Best regards
Steve
