When attempting to do a manual build of u-boot for a DART-MX6 SOM mounted to a VAR-DT6CustomBoard, as described in Sections 8.2 to 8.3 of the Wiki: http://variwiki.com/index.php?title=VAR ... ader.C2.A0
I get an error when I enter the command:
The error is:
make: *** No rule to make target `mx6var_som_sd_android_defconfig'. Stop.
#### make failed to build some targets ####
If I change this command to:
this works without error, so maybe the Wiki needs updating?
I can then go on to enter the command:
This also completes without error, except no SPL file is produced as stated in the Wiki. I am also confused by the last few lines of the output from make:
#### make completed successfully (11 seconds) ####
The CFGS line refers to mt41j128.cfg, but mt41j128.cfg is for DDR3 type DRAM. The DART-MX6 SOM uses LPDDR2, so surely using the config for DDR3 isn't correct?
How can I be sure what register values are used to set up the iMX6 during initial boot?
