<mrjay>
i've found a dead beaf in rk3066 bootrom :-)
<ayaka>
mrjay, do you need a crew driver to fix it?
<mrjay>
nope i only found it there lying
<ayaka>
oh, it is a Chinese joke, you may not understand. The joke is some people without bootloadable floppy disk
<mrjay>
ok
<ayaka>
asking a empty disk and a magnet, after a day, people saw he is playing game
<ayaka>
it is a good joke about repairing computer
<ayaka>
anyway, would you like to public it
<mrjay>
rk3066 bootrom? nope it's better if nobody looks there
<mrjay>
0xdeadbeaf is a rk3066 bootrom command to bring up secondary cpu
<mrjay>
i think :-)
<ayaka>
mrjay, how do you know that? I though there is no way to track the bootrom as it is internal of the chip
<ayaka>
also I don't read every chapters of the TRM carefully
<mrjay>
you can dump the registers with a rom
<mrjay>
0x10100000 is a bootrom start adress on rk3066
<ayaka>
mrjay, wow, amazing, I don't have much time with the boot part now
<ayaka>
mrjay, I think that address has been remap
<mrjay>
not by u-boot ... i dumped it using uboot
<LongWork>
ayaka : still awake ?! man must be dman late :)
<LongWork>
damn*
<ayaka>
LongChair, I am debugging my driver
<ayaka>
recently I am too exciting to sleep. It is usually when I have something want to do
<LongWork>
hehe
<LongWork>
planning on checking more the mpp stuff we discussed tomorrow ?
<ayaka>
ok, I would arrange a time for that
<LongWork>
sweet thanks ! :)
<ayaka>
you are welcome

phh have you ever meet this
<ayaka>
reading the register of the VPU will crash the system
<ayaka>
I think both the power and clock is on or I can't register the interrupt handler
<phh>
Nope never had that
<phh>
I've never had any other problem than iommu stuff
<ayaka>
what is the rate of a aclk in vcode class
<ayaka>
I found it may run at 200MHZ
<phh>
well the clock is in dts
<phh>
not in the vcodec code
<mmind00>
mrjay: the 0xdeadbeef in there is a mark the bootrom checks after having loaded the 1st 1KB, before continuing on to return to the bootrom
<mmind00>
mrjay: or more exactly, which the first part of the loader seems to check, as some sort of selftest
<mmind00>
mrjay: reading further, yes that is also used when doing smp bringup through the bootrom ... I guess it will work the same as the rk3288 is doing right now
