Hello Tomas
There is the document described how to make pppd work on Armadillo-J. It
may help you but Japanese.
http://armadillo.atmark-techno.com/armadillo-j/memo/DialupRouter/uClinux-dist-router.patch
Its summay is below,
1. Prepare three files
- uClinux-dist-aj200xxxx.tar.gz
- ppp-2.4.1.tar.gz (ftp://cs.anu.edu.au/pub/software/ppp/)
- uClinux-dist-router.patch
(http://armadillo.atmark-techno.com/armadillo-j/memo/DialupRouter/uClinux-dist-router.patch)
2. Type some commands along to explanation below
- tar zxvf ~/uClinux-dist-at200xxxx.tar.gz
- cd uClinux-dist
- tar zxvf ~/ppp-2.4.1.tar.gz -C user/
- patch -p0 < ~/uClinux-dist-router.patch
- chmod 755 vendors/AtmarkTechno/Armadillo-J.Base/etc/rc.d/rc.start/*
3. Modify some files to change setting
- vendors/AtmarkTechno/Armadillo-J.Base/etc/default/options
- vendors/AtmarkTechno/Armadillo-J.Base/etc/default/dial
- vendors/AtmarkTechno/Armadillo-J.Base/etc/default/chap-secrets
4. Compile
- make menuconfig
I hope it helps you and pppd works well.
