Revision as of 09:56, 30 July 2019

[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.

50-udev-default.rules - gets installed over the original file.

[SOLVED] Note 7

  • Problem:
Ethernet driver's structure has changed. It was split into several files.
Lives at /driver/net/ethernet/cadence/
  • Soluton:
For out ethernet chip (Atheros 80xx) a fixup had to be added to disable SmartEEE.
It's a single function, call and a couple defines - added all back to the new driver structure.
