看到fix MT7981 available DDR4 size and adjust DDR_SIZE choices in Config.in 是指MT7981不能支持2GB的DDR4吗

是的,在CMCC RAX3000M eMMC上使用2GB的三星K4AAG165WA-BCWE颗粒,只识别到1G。也咨询了MTK维护ATF和uboot的hackpascal大佬,MT7981 DDR4最大支持1GB。 https://forum.banana-pi.org/t/tutorial-build-customize-and-use-mediatek-open-source-u-boot-and-atf/13785/87

好的,感谢大佬回复。我也在几个MT7981的机器上试了2GB的颗粒,都只识别到1G。我以为是颗粒或者BL问题呢。

对于MT7981,是否支持DDR3 1GB大小的内存呢?试了H5TC8G63AMR-PBA,只能识别出512MB大小。
