Raspberry Pi 3B+ (Plus) - Compatible?

[Substring]

@mickaelm i've been saying numerous times we are not yet compatible with it

@mickaelm Pi3B+ only came out a few days ago. Give it time.

[gkralicek2]

@dark_néo
arm_freq=1600
gpu_freq=500
core_freq=500
sdram_freq=500
sdram_schmoo=0x02000020
over_voltage=4
sdram_over_voltage=2

With these, temp is very close to 80 degrees when running emulators like reicast for a while. But so far it held up well without freezing on most of the cards i tried.

@substring is there a way to edit the files to get it to work while it gets updated? as retropie works but wifi dodgy, keep up the good work its appreciated

[Substring]

@dessy i'm not sure, i don't have a 3b+ myself. If it's just a dtb, give a go, it's a costless effort

[Dessy]

@substring no probs might have a fiddle then

[Substring]

@dessy yeah but i don't think it's enough. I'm working on a big system update may b*mp all this myself and hope a 3b+ will arrive soon

@gkralicek2 did you use any heatsink or cooling soultion to get 1,6 ghz on the new pi3 b+?

@substring recalbox is the only OS i would like to use on the new pi3 b+. so hopefully an compatible update will come soon.

[Substring]

@monero i need a 3+ first !

[Dessy]

@substring if you need any log files etc submitting let me know if it'll help

[gkralicek2]

@monero Nope no heatsink. Heat control is very good on the new B+. On the standard Pi 3, even when putting heatsink one could barely let his finger on the CPU without burning himself after a few hours of use. On the current B+, the CPU is hot when touching it but not "burning hot" (even when CPU inner temperature is very high, dissipation is well handled and doesn't give the impression the whole unit is gonna melt :=)

[Substring]

@dessy sadly it won't help as it's a matter of how the kerbel detects the board. You'd need an UART to be helpful as of now

In Retro Pi 4.3.15 the Kernel modyfied and work well on New Pi 3 B+. Did this help us for recalbox ?

[Substring]

@gameboy nope, because we're on kernel 4.4 we'd need to b*mp to 4.9, adapt kernel patches and rebuild. I'm working on it

[Gaetan]

@substring Maybe it's a bit early for you to give the answer, but maybe you'd know already.
Will it be the same Recalbox .img file to burn on both pi3 B and B+ or a different one ?

[Substring]

@gaetan i think it should be the same, can't be sure yet. It's mainly a dtb change (+ major kernel change concerning recalbox)

[Gaetan]

@substring Thank you for the answer. Specially when I like it

[hex12]

@substring sorry but i am really curious to know if improvements on pi3 b+ will reflect in updated performance on recalbox, in particular in n64 emulation. Except the 200MhZ CPU speed, what i think could be useful is the improvements in termal, which i read should bring to a 1,2GhZ stable speed of Pi3 b+, where normal Pi3 should decrease to less than 1GhZ. For sure, as GPU doesn't change, there won't be a high performance increase on emulators, but maybe framerate could be a little more stable on emulators that requires more system resource and most of all if we user active dissipation (heat sink+fan). If you have some datas on that and can share, it should be good to evaluate differences with the two Pi3 models on our favourite applicaton

[Substring]

@hex12 ain't nuttin' voljega shared a benchmark showing some interesting improvements. Gralicek2 said they can ve nicely overclocked. So all in all, you could reach 1.5Ghz, maybe 1.6. I can't tell if it's good improvement, and we sadly have no benchmark suit available (tjat's something i'd love to write but we lack devs)
