Building OP-TEE OS for pine64-LTS - foreverska - 12-13-2019
I am attempting to add a mk to OP-TEE/build for the pine64-lts. I'm pretty far along but have some fairly sticky faults. The first was the transition from ARM-TF to optee_os failed. So I sent some emails off and focused on something I thought would be easier, booting Linux.
What I've done is copied and modified the build script from qemu with concepts from other boards (poplar, rpi3) and brought in mainline u-boot. U-boot is made aware of ARM-TF and the board readily boots the resulting .bin. Next I wrote and compiled a boot.cmd:
Code:
setenv bootargs earlyprintk console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10
load mmc 0:1 0x44000000 /sun50i-a64-pine64-lts.dtb
load mmc 0:1 0x42000000 /uImage
bootm 0x42000000 - 0x44000000The dtb is from the kernel source. It seems to be okay with all of this except when it boots the following is printed.
Code:
switch to partitions #0, OK
mmc0 is current device
Scanning mmc 0:1...

As it always happens as soon as one asks, they find their way.
Changed kernel version and now it works save some issues with getty trying to start on ttyAMA0 rather than ttyS0. Which I can fix by hand, working on how to make it work out of the box.
