<dvergatal> mmind00: i have compiled the u-boot with bl31.elf and tee.elf and now i don't understand the rockchip manual for writting the spl into emmc and have questions can you help?
<mmind00> dvergatal: the build should've produced two files: idbloader.img and u-boot.itb
<mmind00> dd if=idbloader.img of=whatever seek=64
<dvergatal> mmind00: yes it has generated
<dvergatal> hmm do it on sd card?
<mmind00> for example ... I'm still collecting the second part though
<dvergatal> mmind00: fot this i will need an extra card, i was rather thinking to write into emmc memory
<mmind00> in your u-boot .config you have a variable CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR
<dvergatal> 0x4000
<mmind00> convert that to decimal and do
<mmind00> dd if=u-boot.itb of=whatever seek=that_value
<dvergatal> mmind00: only these 2 files?
<mmind00> yep
<mmind00> idbloader.img contains the tpl+spl and u-boot.itb contains u-boot, atf and tee
<dvergatal> ok no any other need for rockchip loader?
<dvergatal> mmind00: because in here https://github.com/u-boot/u-boot/blob/master/doc/README.rockchip it is written for spl to write this rockchip loader also
Ke has joined #linux-rockchip
<mmind00> as you noticed the idbloader.img gets created by the build-process nowadays
<dvergatal> mmind00: yes that is right, that is why i am so confused, these howtos are, i'm sorry for the word, but rubbish
<mmind00> dvergatal: they don't receive to much love it seems
<dvergatal> mmind00: in one it is written something in second one it is written something completly different
<dvergatal> midnight: yeah, i suppouse
<dvergatal> sorry midnight it should be to mmind00
<dvergatal> :P
<dvergatal> mmind00: ok i need to find some sdcard to check it out, it would be also a better solution for me to write into it than erasing/flashing this emmc
<mmind00> dvergatal: which is why I put my build environment into scripts https://github.com/mmind/boardfarm-scripts/blob/master/kernel/bootfarm-helpers.sh#L652 ... I don't spend too much time in u-boot land
<mmind00> dvergatal: yep, personally I do prefer sd-booting for development purposes as well - it's way faster
<dvergatal> :] thanx mmind00 i'll go find some and answer to you later on

<dvergatal> mmind00: mine sd card is as mmcblk0 and there is one partition mmcblk0p1
<dvergatal> mmind00: should i remove this partition?
<dvergatal> mmind00: besides that if i inputthe sd card into card reader on the board it doesn' boot from it but from emmc
<DuClare> wipe the bootloader from emmc
<dvergatal> i'm sorry i was wrong it boot's first from the card but there is some error
dstzd has quit [Quit: ZNC - https://znc.in]
<dvergatal> ukleinek: yeah now i see it boots from tpl/spl
dstzd has joined #linux-rockchip
<dvergatal> mmind00: ok now it boots but as you have mentioned earlier i should use optee <= 3.7.0 and i have used 3.11.0 and it is stucked :P
<dvergatal> mmind00: and i was woundering if i can only copy plat-rockchip folder from 3.9.0 to 3.7.0? is that sufficient?
<dvergatal> wondering*
<dvergatal> mmind00: yeaahhhh you were right now it works :D
<dvergatal> mmind00: big thx you're the best :]

<mmind00> stikonas: depends on the usage ... personally I'd also see no use, but there are use-cases where you want to hide stuff from the main OS
<mmind00> (DRM-decryption-stuff being the prime example)
<mmind00> dvergatal: great to hear
