13:25 <CounterPillow> macromorgan: are there any Anbernic RG353P schematics floating around?

13:25 <macromorgan> unfortunately not, Anbernic never gave those out

13:27 <CounterPillow> Aw :( Well I guess I just need to know whether there's some maskrom testpads to short. I've figured out I can hold down one of the volume buttons to get its vendor u-boot into loader mode

15:40 <CounterPillow> oh you know what, I think the F-button can put it into maskrom mode, it's connected to SARADC VIN0 and judging by the press threshold you have in the DTS that'd be around where I expect maskrom to see it as "please enter recovery mode"

15:43 <CounterPillow> ok nope, voltage must be slightly too high for that

15:44 <qschulz> CounterPillow: are you sure rk3566 supports selecting the boot medium from SARADC?

15:44 <qschulz> I know RK3588 does, but I'm not sure about other ones

15:45 <CounterPillow> qschulz: most likely yes on account of RADXA using this design on ROCK 3C.

15:46 <CounterPillow> it's possible though that that's still their vendor bootloader thing, and the maskrom doesn't read it on RK3566

15:47 <qschulz> CounterPillow: https://dl.xkwy2018.com/downloads/RK3568/RK356X/Hardware/Rockchip_RK3566_Hardware_Design_Guide_V1.1_EN.pdf

15:47 <qschulz> 2.1.5 System Boot Sequence

15:47 <qschulz> no support for the ADC stuff

15:48 <qschulz> so you need to short clock/data lanes of your boot storage media to enter USB boot mode

15:49 <CounterPillow> Urgh, that's unfortunate

15:49 <qschulz> on Radxa Rock 4D, you can see the first channel is called SARADC_IN0_BOOT

15:49 <qschulz> and they are NOT connecting the RECOVERY signal to it

15:49 <qschulz> that's a pretty good hint

15:49 <qschulz> so RK3576 seems to have that support as well

15:49 <CounterPillow> Yeah, I know RK3576 does

15:50 <qschulz> (I didn't :) )

15:51 <qschulz> RK3528 (and I assume RK3526 I guess) seems to have it

15:52 <CounterPillow> RK3562 probably does as well, basically anything RK3588 onwards

15:52 <qschulz> I would assume so, it's a pretty nice feature to have :)

15:54 <CounterPillow> guess I'll be probing around for convenient eMMC test pads

15:56 <CounterPillow> Speaking of which, if anyone wants to make a RK3576 handheld feel free to send me one c:

15:56 <qschulz> CounterPillow: looking at the datasheet of RK3562, RK3566 and RK3588 it seems like it supports that kind if you find a pin named SARADC.*0_BOOT

15:57 <qschulz> CounterPillow: why specifically handheld :) ?

15:57 <macromorgan> what handhelds are using the rk3576?

15:57 <CounterPillow> macromorgan: none that I know of :(

15:57 <CounterPillow> qschulz: because I already have SBCs using it

15:58 <macromorgan> ohh, gotcha

20:03 <CounterPillow> not looking good for my chances to get at eMMC D0 or eMMC CLK

20:31 <Dex2x> So curious the new orangepi 6 won't be a rockchip, I mean rockchip going forward with new chips was a question, but i guess now it's an even bigger one?

20:50 <CounterPillow> what?

20:50 <CounterPillow> did you miss https://www.cnx-software.com/wp-content/uploads/2025/07/Rockchip-RK3668.jpg

21:13 <Dex2x> No, but there was some rumors saying they going to focus on military and car industries

21:36 <Dex2x> That still seems a bit slower than the ARM CIX CD8160 or ARM Cix CD8180?

22:44 <Dex2x> I see mention of a RK3888 but can't find any details yet
