<lvrp16> anyone from rockchip can comment on rk3229 upstreaming?
<phh> first, please note that rk3328 ~= rk3228 ~= rk3229
<phh> and current mainline dts has i2s, spdif, uarts, i2cs, mali, vpu (I didn't know vpu dts had been mainline), mmc, usb, ethernet
<phh> it is notably missing video output
<phh> please note that vpu and mali are NOT supported by mainline drivers even though the dts is mainlined, though other components should be good
<phh> ah no, vpu is not in the dts, only mmu
<mmind00> Also, there are no usable (small) dev-boards for the rk3229
<mmind00> So it's slow-going ... I've ordered a rk3229 tv-box which should hopefully turn up in the next days
<mmind00> U-Boot support is half complete ... with the sdram patches posted to the uboot list
<mmind00> rk3229 OP-TEE support, doing PSCI on rk3229 is in the upstream OP-TEE repo as well
<mmind00> lvrp16: ^

<lvrp16> phh: thanks, thats very good progress
sunxi_fan has quit [Read error: No route to host]
<lvrp16> mmind00: we are thinking of doing a development board for that chip. we also have a bunch of tv boxes with that chip
<mmind00> lvrp16: great to hear :-)
wzyy2 has quit [Remote host closed the connection]
<mmind00> lvrp16: as I said, Rockchip did a lot of work to get the lower levels in order (uboot, op-tee) ... also core graphics support also is in the kernel already [https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/rockchip/rockchip_vop_reg.c#n434], so getting graphics shouldn't be to big a problem
wzyy2 has joined #linux-rockchip
<lvrp16> the only question is whether to do a iot board or a slightly bigger board the size of a tv box
<ayaka> lvrp16, have you look on the rk3036?
<ayaka> usually the performance of the low price chips from rockchip is poor, but it doesn't have a high standard on the electric signal
<ayaka> so you can reduce the size of the board easily
<ayaka> also the rockchip has the MCU serial which could support WiFI but the SDK is not open to public I think
<lvrp16> thats 40nm
<lvrp16> and kind of obsolete, may be too old for investing time
LargePrime has joined #linux-rockchip
<ayaka> ping me when you are back, stdint are available on that time I think
<ayaka> lvrp16, it is not obsolete, you could still order it
<lvrp16> i mean i think 40nm products are just dying a slow death. do you know pricing on the rk3036?
<ayaka> I don't know, but I think it is quit cheap, as much cheap than rk3229
<ayaka> it depends on what the produce do you want to made, for the IOT, I think the total price and the power are the first criterion
<ayaka> if you don't need any graphics or video capability, I would suggest to choose a MCU for those job
<ayaka> mmind00, the open-TEE really mad many people, they will be happy to hear of that

<ayaka> lvrp16, also there is a rk3128 for you, it has a low power variant

<lvrp16> ayaka, are any of these pin to pin compatible or all require different board layout?

<ayaka> lvrp16, I don't know, but I think they require a different layout but having many similar place
