Raspberry Pi 3B+ (Plus) - Compatible?

[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 :=)

@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

@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)

@hex12
take a look at this little review:

i've received today my new pi3 b+. libreelec and raspbian works. recalbox not.

@substring you got your pi3 b+ already? im so hyped to test the new performance on recalbox.

[Substring]

@dizell we have an internal build working fine on pi3+, needs some fixing here and there, nothing bad. The real problem is that we can't include it in the current build as any kernel update would brick recalbox. Working hard on finding a solution without forcing people to reinstall from scratch

Thanks for your amazing work.
But don't worry, reinstall from scratch is not a big deal!

@noktambule @substring

Same for me, New Pi 3B+, and new fresh install to go with it! I have this obsession that new installs are always better than upgrades! I have the same thinking when updating my IOS devices

Thanks for all the hard work guys, appreciated

[Substring]

Pi3b+ forces us to switch to kernel 4.9 (we're on 4.4), and in the coming weeks, raspberry should switch for good on 4.14. So we can't always get that late comparing to official kernel releases. That's also forgetting the x86 kernel release cycle is much faster ...

So i'm working on a new update process

[kazki]

that's a good thing to know that a internal version of recalbox works with R3B+
I'm building a second bartop and I'd like to use the new raspberry pi 3B+
it's quite irrelevant to install recalbox from scratch since you always advised to use usb drive to store roms, of course it takes longer to load but I think it's worth the wait at every boot: I can manage my roms on a usb drive directly (adding and more often deleting titles from a full set, I know I should own the originals and so on)

I tried retropie since the beta is compatible with P3B+ and to my humble opinion although it's really nice to be able to set every thing, I really appreciate the simplicity of recalbox

Thanks for your efforts guys, I'm looking forward to installing recalbox on a new R3B+

[roman126]

@kazki agreed, how much longer does it take to load from USB? Twice as long, 3 times as long?, maybe I should try and find out for myself , yes the very thought of trying to get all the roms off my memory card, to do a new build for 3B+ when it’s available fills me with dread. Time to invest in a decent Nano USB memory stick!

[kazki]

@roman126

i just chronometered
it took about 1min25sec to boot from usb drive on (i used a USB3.1 64GB Sandisk USB drive Sandisk Ultra fit newest version)
compared to under 30 sec with a Sandisk Ultra micro sd card

It can take a while to transfer roms through ethernet I think it's easier to manage my roms library from usb drive. That's not really the subject here so I won't develop

[roman126]

@kazki true, thanks I’ll give it a whirl
