For Sale / Wanted / wtb: 68HC11 "tiny" board
« on: February 26, 2021, 12:29:19 pm »
Years ago on eBay there were small and tiny 68HC11 boards. Nowadays it seems there is only something located in the US, and it's almost some Motorola kit, so too big for what I'd like to do.

Grifo in Italy has still something for sale, but they ask 250 euro shipped and this is really crazy price.

I am looking for a little 68HC11 board, with at least 8Kbyte of ram, and 8Kbyte of ROM.

If anyone has one for sale, or know where I can buy one, please let me know. My max budget is 130 euro shipped.

Zaurus - Hardware discussion / C1000, C3000, C3200: memory layout
« on: January 28, 2021, 10:10:46 am »
I have never investigated about the memory layout, but I'd like to know how the flash is organized and if it's possible to erase everything in order to install uboot with some of its "save config" area.

I prefer uboot on a serial console, bootstrapping a kernel from the network, or from the microdrive.

As well as I understand, the CPU boots from a ROM, is it correct? if so, where is it mapped? At which address? And where does it jump?

I did something 11 years ago, and since then I have been using my C1K as user, I have never touch kexecboot and similar since then. I remember there was a size limitation for kexecboot, I don't remember what was the reason.

Let me know. At the moment I am compiling Gcc, Go and Ada, and I am cleaning and updating my old 2010 Gentoo-stage4 rootfs in order to have something clean.

For Sale / Wanted / wtb: miniPCI USB2 EHCI, Nec chip
« on: January 25, 2021, 03:08:48 pm »
I don't know if this is the right place to ask but ... I am really in a big trouble with a hobby project I am running because the project is based on the RB532 router and ... there is no USB port to connect an hard-drive.

The router has three 10/100 ethernet ports, they are all sued, and even if I had a fourth one available I couldn't use NFS for this stuff, and I cannot change the router with a modern model, long story about reasons, but at this point I'd better find a workaround.

I know there where some miniPCI USB2 ECHI modules around in the mid 2000s, with a NEC chip on them. Sadly I cannot find one on eBay (I have been looking daily for 1 year).

Does anyone, by any chance, have one for sale? Or does anyone know where to buy one?

Thanks :D

Looking to include a couple of programs written in Go to the Zaurus userland.
Before trying to crosscompile GccGo to have native GccGo compiler, I'd like to know if there is already a bootstrapper.

Please let me know  :D

In order to compile gnat you need a gnat compiler, it's the chicken and egg problem.

I have solved it for HPPA-v2(1) but it cost me one year of attempts (cross-compiling parts from x86 and somehow making them HPPA-native until everything was able to recompile itself autonomously) and before investing all this time for my old Zaurus C1K I'd like to hear if there is already around a gnat binary profiled as "armv5tel--linux-gnueabi".

(1) it's my daily RISC workstation. I know, I know ... x86/64 bit is better, faster, and cheaper, but I love my RISC workstation, especially now that's finally able to compile ada sources! And I also want my PDA to be able to compile ada sources  :D

is there any attempt to use uboot as bootloader?
I'd like to use the serial console.

Let me know.
