Hi Vojtech,
Thanks for your interest in LPC, and for asking this question!
MCUXpresso SDK for LPC8xx devices is coming ... we are planning to release this in Q2 this year. The SDK provides the HAL abstractions as provided in LPCOpen and STM equivalents. Along with it will come the same MCUXpresso configuration tool support that is in place for Kinetis and LPC54xxx family devices already.
Code Bundles are intended primarily for customers who are migrating from 8 or 16 bit designs, and/or prefer to work from a register level.
LPCOpen packages for devices released before 2016 will continue to be available, but are not being further developed.
Regards,
Brendon
