So, if this is 2.4 then I will definitely buy it for 100 euro, and I will borrow one-two Turing RK1 from my current boards for testing. Eventually (not this month, busy home budget) I will buy four of CM4 modules and I will have three boards in fleet 🙂

BTW, I am curious. I several times consider RADXA, compare with Rarpberry it has fully functional normal PCI-E, but each time when I want to buy it I found literally zero supply on all shops, except the very questionable chinese shops (not even alibaba or aliexpess or arace, some trashy one). Why?

it is 2.4 - there was bug when released so all 2.4 have adapter fix in button battery slot.

also only 2 buttons, 2.5 has three buttons

could you please explain a little bit more, what is the bug and what is "adapter fix in button battery slot"?

Or rephrase, maybe my english not good enough to understand sentence

i have two boards from kickstarter and both have this fix. i dont know if they fixed it later for 2.4 but it was definetly fixed for 2.5 (The RTC battery fix is integrated with the board and the RTC Battery Adapter Board is no longer needed)

Wow 🙂

Thank you

The very early 2.4 shipments had the battery fix sent out for DIY soldering, later 2.4 shipments had that battery adaptor and resistor soldered at the factory before shipping. Also, some kickstarter backers could select to NOT have the NVMe headers added to the bottom of the board (I think it was like $10 more to add the headers). If the intention was to only have CM4 in the board the NVMe is not accessible anyway. 2.5 always has the NVMe and the battery is fixed (plus the other changes like USB, etc.).

@excavador - I have both 1x 2.4 and 1x 2.5. I am running v2.48.0 with rollback v2.44.0 on both boards. On my 2.4 the BMC storage is red at "23.84 MB / 23.86 MB". Is that expected? Is there a way to manage storage better? Perhaps either (a) reduce the size of the firmware or (b) delete the rollback manually after the newest version is confirmed working?

Also, if you have not found anyone with 2.4 to do testing for you... PM me.

No, not expected 🙁

I wrote to person from tweakers. He lives in two hours by train from me and he posted ink two days ago high chances I will buy board in few days

I will write you if this deal will not settle down or if I will not find alternative buying

I just need to buy this second hand 2.4 board, put turing rk1 module inside + serial cable, and wire my AI to investigate the differences and propose the solution I will write you directly after that to collect all list of pains 🙂

If you want CM4 modules, this one has them included https://tweakers.net/aanbod/4195218/raspberrypi-kubernetes-cluster.html

Im still hoping for one with RK1 to pop up for a good price haha

Also wrote this guy 🙂 Previous link no answer yet

waiting

We agree with @shadowbumble about board with CM modules, thank you for reference @svenvg93 ! As soon I figure out something on my side, I will get this 2.4 board with CM modules and will wire it to firmware and fix the issues 🙂

Correct, this one is from the second batch of the v2.4 with the fixed resistor and the battery adapter 🙂

Update such cause problems ?

Not sure I understand your question?

I have kickstarter version with battery adapter . And think should I update official firmware.

Ahh. I am very happy with the excavador firmware on both my 2.4 (kickstarter) and 2.5 boards. It feels like the original promises being fulfilled. Currenlty I am running v2.48.0 on the 2.4 and have had no issues.

Thank you for warm words

@excavador thanks for this bmc FW. Just upgraded my 2.5.2 board few minutes ago, process was seamless. New features are really great. Thanks again for the good work 😉

You are welcome, and please report bugs or feature requests!
