I built a custom image from the latest sources for the imx6q-sabresd board. The image works fine but I'd like to change the u-boot to initialize the dram to a slower speed so we can test if our software will continue to perform properly. There are a number of posts with this same question but the version of u-boot seems to be quite a bit different. I'm using 2018.17. The older posts refer to flash_header.S or a various DTC table versions which don't seem to have changed in the latest version. Either that or I just don't know where to look which could also be the case.
Anyhow, anyone have a quick pointer to the right sources to start looking at?
Hi Dennis
2018.17 version is not supported by nxp, it may be posted on uboot mail list.
Latest nxp official uboot version is v2017.03_4.9.88, I am afraid it does not support
changing ddr frequency
Best regards
igor
