How to change u-boot.imx start address ?

mehmetipin — Fri, 20 Jan 2017 07:57:35 GMT

Dear community,

We have a mx6DL board. I can download and run u-boot 2009; I downloaded the 2014 u-boot.imx, but it could not start; I noticed System.map file of .imx and .bin files are different(0x17800000 vs 0x27800000). I hope, I have u-boot-2014 to run, if I change start address to 0x27800000; but I don't know the way to do it.

Could anybody know, please help me.

Best regards.

Mehmet Ali Ipin

Hi Mehmet

one can check uboot loading procedure in denx uboot documentation or for example
http://stackoverflow.com/questions/35336940/understand-u-boot-memory-footprint
so one can try to change
#define CONFIG_SYS_TEXT_BASE in uboot/include/configs/board/mx6sabre_common.h

Best regards

Dear Igor,

Thank you very much for your answer. I can see the map file variables are started from 0x27800000, but loading and jumping adresses are 27FF_F400; so u-boot messages are not seen on serial terminal. I woul be very grateful if you know how I can set them to 0x2780_0000 and 0x2780_0400? while I try to understand your stackoverflow link.

Thanks and best regards.

Mehmet Ali
