Change memory from 512M to 256M

lixiao — Sun, 31 Dec 2017 16:47:21 GMT

I change the imx6ul evk board's ddr3 from 512M to 256M.The memory type is Samsung K4B2G1646F-BYK0.I config the register using the tool I.MX6UL_DDR3_Script_Aid_V0.02.xlsx like this:

But when i use the RealView .inc generated by this tools to programe using mfgtools,the kernel crashed causing by the memory.This is the log:

Did anyone meet the same problem？How did you solve this problem?(The attachment is the datasheet of the ddr3)

Re: Change memory from 512M to 256M

igorpadykov — Wed, 03 Jan 2018 07:23:48 GMT

Hi Charles

for using new board with mfg tools it is necessary to rebuild mfg tools

(please use sect.6.2 Manufacturing Tool, MFGTool attached Yocto Guide)

firmware (files in /firmware folder) with new ddr calibration coefficients (found from ddr test)

in uboot/..mx6ul_14x14_evk/imximage.cfg.

Best regards

Hi,igorpadykov:

I have checked, the problem is not caused by no calibration.Thanks for your help.I have found the reason.I allocation 128M to the cma config ,but the total memory is 256M.The cma allocation is too large, resulting in insufficient system memory, so kernel can not start normally.
