New page

==Note 1==
* /dev/xdevfg got obsolete - there's fpga manager instead which cannot load *.bit (only *.bin or *.bit.bin)
* '''Solution:'''
Brought back the old driver (drivers/char/xilinx_devcfg.c)- it works

==Note 2==
* php 5.6.40 - EOL and won't build
* '''Solution:'''
Disabled mysql extension:
To meta-elphel393/recipes-devtools/php/php_5.6.%.bbappend:
PACKAGECONFIG[mysql] = "--without-mysql --without-mysqli --without-pdo-mysql"
CFLAGS += " -ldl" Oleg
