Contents
[SOLVED] 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 and edited Kconfig and Makefile)- it works as it used to
[SOLVED] Note 2
- php 5.6.40 - EOL and won't build - mysql supposedly moved header files.
- 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"
[SOLVED] Note 3
- New package rng-tools is whining: Failed to init entropy source hwrng
- Solution:
Leave as is for now. The full log is: Initalizing available sources Failed to init entropy source hwrng Enabling JITTER rng support Initalizing entropy source jitter
- Comments:
- Haven't found if Xilinx uses any driver for /dev/hwrng
- TODO: Find out if the order of entropy sources can be changed
- Note 4
- php, what's that?

SOLVED Note 5
- MAC is not read from NAND, displays the default: 00:0e:64:10:00:00
- Problem?
[ 3.639851] elphel393-init: Flash page read, code -95
- Comments:
- Lookup what had changed.
- Solution: (for xlnx_rebase_v4.14 branch of linux-xlnx):
In drivers/mtd/nand_base.c in nand_scan_tail() they call nand_manufacturer_init() which is mapped to a new driver drivers/mtd/nand_micron.c. So, when it fails - the driver init fails - mtd functions do not get assigned. (And the driver (drivers/elphel/elphel393_init.c) that reads from OTP area returns -95 which is EOPNOTSUPP.) We just need to fall through for a quick fix.
The reason that function exits with an error is it decides that it does not support forcefully enabled on-die ECC. And this needs to be investigated.
