18thApril24 Pi Beta ROM Mod init failure

So I have updated the Beta ROM on a Pi2B from one dated 26th March 24 to the latest beta , 18th April 24, and when it does the ROM modules init it data aborts just after Init Mod GPIO with:

mod init doneerror: Data Abort:Abort on data transfer at &FC19622C (Error number &80000002).

*Where gives:

Address &FC19622C is at offset &00013CC4 in Module SharedCLibrary

Same here on an RPi4B. A local build also failed.

Data Abort:Abort on data transfer at &FC19622C (Error number &80000002).
Address &FC19622C is at offset &00013CC4 in Module SharedCLibrary

If you do a *ShowRegs and look at R14 that tells you who the caller was, and that’s EtherUSB. If you disassemble a bit either side of R14 there’s a constant string loaded into R1 which is “CONF”. If you look in the EtherUSB sources, that narrows it down to 1 line, and a NULL pointer dereference if the options string is unset.

I have a Pi 3B to hand and have put a fix in this ROM if anyone fancies trying it out on a 2B or 4B, let me know if it helps and I can submit my change to ROOL.

That is fine on the RPi4B.

a fix in this ROM

+1 OK on my Pi2B now so thanks for the quick fix :-)

I just updated my Pi 4B to the 18th April nightly (I hadn’t spotted this thread at the time), and got the same results as Doug.

Sprow’s fix above also resolved it for me.

Can anyone tell me please what to do with the fix. I downloaded it on a Mac, where do I put it on my Pi 4B?

It’s rippled through to the nightly builds now, so you can just use the one off the downloads page again. The file riscos.img is the one that changed, that lives in !Boot.Loader on the SD card you boot from (which when viewed on a PC or Mac would be on the drive called PiBoot).

That did the trick, thank you.
