Hello,
I am using dvrrdk with DM8148.
I try to enlarge the memory for kernel (it uses bld file for this issue).
But before doing the bld changes, I just changed in bootargs from
"... mem=128M "
to
"...mem=128M@0x80000000 "
It seems to get stuck during kernel boot:
.....

I also see in memory map that linux should start in 0x80000000 :
./build/dvr_rdk/bin/ti814x-evm/dvr_rdk_m3vpss_release_512M_128M.xem3.map
Is there any idea why the additional @0x8000000 , caused this crash ?
Regards,
Ran
