I know it is too late to reply. I am not expecting miracles since this is complicated and comes w/ years of experience from sources around the net, u-boot, and how u-boot signifies itself of am335x_evm_defconfig.
“I am on to something,” as usual but w/out working order, I am bit slow to duplicate for now.
I get a version of a cross-compiler (GCC), u-boot (u-boot), and a kernel set up (Linux).
I am testing now w/out any help. This is why I am reaching out:
The m-tune= ‘switch’ seems to want something outside of what is available, i.e.
Anyway, I am sure someone is familiar w/ this issue as of the current, bleeding edge u-boot being shipped these days, along w/ an updated kernel, and no prior experience in building.
P.S. I am following along in your, whomever, eewiki Pages for the BBB. They seem very workable and well thought out but when I exchange out what you have produced w/ a new Kernel or u-boot version, I run into errors. Is this normal?
