Doubts about Bootloader - tuxd3v - 12-07-2019
Hello all,
I have tried to build Rockpro64 bootloader..
But I am still confused with the methodology/ tools used..
I am using ATF mainline + u-Boot..
But it seems that the boards uses OPTEE Trusted Execution Environment instead of ATF?
Is this scheme bellow correct?
Code:
+--------+----------------+----------+-------------+---------+
| Boot | Terminology #1 | Actual | Rockchip | Image |
| stage | | program | Image | Location|
| number | | name | Name | (sector)|
+--------+----------------+----------+-------------+---------+
| | | | | |
| 2 | Secondary | U-Boot |idbloader.img| 0x40 | pre-loader
| | Program | TPL/SPL | | |
| | Loader (SPL) | | | |
| 3 | - | U-Boot | u-boot.itb | 0x4000 | including u-boot and atf
| | | | | |
| 4 | - | /boot | boot.img | 0x8000 |
| | | | | |
| 5 | - | / | rootfs.img | 0x40000 |
+--------+----------------+----------+-------------+---------+
Does I need OPTEE 'tee.bin'( renamed as bl31.elf )??
I am already using ARM Trusted Firmware bl31.elf..
Can somebody help me?
Thanks in Advance,
Best Regards
