Currently we only have the busybox getty program which not support this feature. We using the yocto env with linux 4.1.8 and... Changing user/kernel virtual memory split to 2GB/2GB I'm using the P4080DS SoC with 32bit 4.18 Linux kernel + RT Patch. While using the Real Time Patch I can't work with HIGHMEM regions (CONFIG_HIGHMEM is disabled by default) so I've changed the virtual me... P3041DS CPU changed (remove / insert) Can the P3041DS Development System CPU be changed (removed and reinserted w/o desoldering) (e.g. change P3041 to P5020)? 
Remapping u-boot in NOR-FLASH P3041 Hello all, I am starting to use P3041 in a custom hardware (very similar with the P3041DS) and would like working with u-boot, but I'm having a problem with NOR FLASH memory addressing. I'm using the Freescal... 
Using sync command upon startup I'm using linux 4.1.8 32bit (yocto env) on p4080ds SoC. On each startup the init process (systemV init) performs mount to a 15GB ext4 fs (nand flash). Later (still by the init process and before getty invocation) th... Design files for p1020rdb-pa Where might we locate design files (layout, schematic, BOM, BSP, etc.) for the P1020RDB-PA? Please note, that this is REV. A of this board. All of the design files I can seem to locate are for more recent revs...
