I tried to replace the DRAM of imx8mqevk board with a 8Gb (1GB) DRAM, which is a 2 die package with 32Mb x 16Dqs x 8 banks x 2 channel. I used the attached *.ds file to test it with the DDR tool v3, then the DDR tool shows the configuration is correct. The log file is attached as the test_result**.log file. Then I  generated the ddr_init.c and ddrphy_train.c and modified imx8mq_evk.h for 1GB. I followed all the flow described in the document and successfully bitbake core-image-minimal. However, when I boot up with the image, I got error. The u-boot log is attached as the "outofmem.log". Please help see what's wrong.
