Re: Linux on CX II CAS Status

Absolute and relative were not working via ll2 afaik.

USB is probably a coincidence, sometimes the bootloader will hang after the boot command.

I will try to do some more testing soon.

Re: Linux on CX II CAS Status

I rebuilt linuxloader and replaced the uploaded version. Thanks for all your help! That does indeed let me specify root=/dev/ram and lets me get to busybox! There are still some issue with the bootloader : ll2 script loader is not working, since any file specified from a script fails to load (maybe...

Re: Linux on CX II CAS Status

Indeed I just tried that, same thing. Weird (initially everything was in the linux/ folder but I moved everything to the root) example .ll2.tns : kernel linux/ndlessKernel.tns initrd linux/newinitrd.tns cmdline root=/dev/ram dtb linux/nspire-cx2.dtb.tns boot EDIT: can load each component manually vi...

Re: Linux on CX II CAS Status

Hmmm, linux-loader2 compiled with the latest toolchain doesn't seem to be able to work with the filesystem. The one you posted and the one I just compiled behave the same, I'm debugging it now. https://github.com/tangrs/nspire-linux-loader2/blob/ca31ca096bea419b687d6d46ec31e6e67a61b7aa/load.c#L37 ke...

Re: Linux on CX II CAS Status

Update: I compiled a small busybox userspace with buildroot and dropbear sshd, the system seems to be working fine except for LCD. There is some drm related error in dmesg : https://gist.github.com/mj-sakellaropoulos/6c510d8df896be80414eab66c4d4f675 I have also noticed SPI address from hackspire wik...

Re: Linux on CX II CAS Status

Nice, that config boots! However, LCD is rotated and corrupted. I can also confirm that the keypad is working. I'm going to try to get a newer busybox next. (screenshot : https://drive.google.com/file/d/1zHzOWEMv0uYgX481hPugb6bdfvMUzF9g/view?usp=sharing) (edit: USB seems to work too) (edit2: can suc...

Re: Linux on CX II CAS Status

Oh nice! I didn't think to look at the branches on your fork. I have compiled it a couple times now with .config from https://github.com/Vogtinator/nspire-linux-configs/blob/master/kernel/devicetree.config and various cross compilers. I'm also using the new nspire-cx2.dts . However it just hangs on ...

Re: Linux on CX II CAS Status

I have searched the mail archive and didn't find anything recent, but I will keep an eye on it.

Also wondering if there is any hardware difference between CX2 and CX2CAS ?

Linux on CX II CAS Status

I have attempted to boot kernel and initrd from https://tiplanet.org/nspire_linux_builds/ using the CX device tree. It does seem to be "kindof" working but the LCD content is garbled (see my post on GitHub : https://github.com/tangrs/nspire-linux-loader2/issues/14) I am wondering if we hav...
