00:50 <smaeul> Lightsword: if you want to parse the BSP cert item, you have to actually parse the not-quite-DER

00:52 <smaeul> mkimage can only validate cert items generated by mkimage. the BSP uses a slightly different hardcoded template to fill in the values (in other words, the BSP doesn't use a real DER encoding library either), so the size/offsets are all different

00:55 <smaeul> the template used by mkimage was chosen to be as small as possible and also work with all known boot ROMs, so the ignored X.509 fields (e.g. the subject) are zero length as much as possible. the boot ROMs do a heinous combination of parsing field lengths and assuming hardcoded offsets.

02:51 <junari> I checked with a voltmeter that the voltage on the axp323 is changing. So it's something else

03:56 <junari> in bsp pmu driver I see set_voltage_time_sel that "abs(new_selector - old_selector) * delay->step + delay->final + 999" where is delay->step = 25 and delay->final = 50

03:59 <junari> On the other hand, it shouldn't be related to delay, since after warm reboot the frequency change works without hangs. So I think BSP code somehow tunes otherwise axp323

10:10 <apritzel> wens: jernej: dammit, the A523 watchdog DT binding and driver changes now made it into Linus' tree, bypassing -next, apparently. So the DT check would now pass, but I guess it's too late now?

10:29 <wens> apritzel: definitely too late

16:47 <warpme> junari : i see https://gitlab.manjaro.org/iuncuim/linux/-/commit/55443006ada7af0c83e6a3c790d8259f03d8e1d3 With this change is cpufreq stable for you?

19:31 <Lightsword> smaeul, is there any reference parser/code for parsing the not-quite-DER structures in the way the bootrom does? like I want to make sure the sunxi-fw parser replicates bootloader logic as much as possible when it comes to parsing

20:24 <loki666> aprizel, jernej: does that looks good https://gist.github.com/loki666/5c4a466c790d1b4016754c4141d13d1d ?

21:51 <smaeul> Lightsword: if you want to match the boot ROM logic, then your reference will be the boot ROM. I can send you my Ghidra projects for a few SBROMs, but that's about it

21:52 <Lightsword> smaeul, do you have ghidra projects for h616/h618?

21:52 <smaeul> h616, yes, probably somewhere

21:53 <smaeul> the only other reference is https://linux-sunxi.org/TOC0 which I assume you've looked at already

21:59 <Lightsword> smaeul, yeah, been mostly looking through that along with u-boot source and bsp sources for info

23:01 <loki666> apritzel: https://gist.github.com/loki666/5c4a466c790d1b4016754c4141d13d1d

23:04 <apritzel> loki666: sure, go ahead (and you don't need to ask, you are doing a good job!)
