What you need
Besides the hardware used in the prev app you will also need:

1 x Tibbit #38 (push button)

Quick jump to start NodeJS development on LTPS boards

Posted 01-18-2017 at 04:55 AM by Dmitry_Slepov

To install it, you should connect to the LTPP board from an SSH client and do the following steps:

Code:

# Setup package repositories (if it's not done already)
smart channel --add a0 type=rpm-md name="LTPS all" baseurl=${RPMSBASE}/all/ -y
smart channel --add a1 type=rpm-md name="Tibbo LTPS general" baseurl=${RPMSBASE}/cortexa8hf_neon/ -y

NEWS 161223
Kernel 4.9-x86_64-exton is my newest Slackware kernel. The stable kernel 4.9 was released by Kernel.org on December 11, 2016.

I have compiled a very useful (as I think) 64 bit kernel for Slackware Current (14.2) and/or all Slackware derivatives. For example Slax, Zenwalk and SlackEX. The kernel is compiled exactly the same way as Slackware’s latest kernel huge. “My” kernel 4.9-x86_64-exton has even more support for new hardware, etc. Kernel 4.9 is the latest kernel...
