Unsupported floating point instruction in kernel?

Took arch/vfp/vfpmodule.c from kernel 4.19

 +
[    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.

 +
==<font color='green'>'''[SOLVED]'''</font> Note 7: Add back fixup for Atheros to updated ethernet driver==
 +
* 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.
 +
 +
==<font color='green'>'''[SOLVED]'''</font> Note 8: u-boot update==
 +
* update u-boot
 +
* solution:
 +
Updated to 2019.07 mainstream u-boot

- converted our *.h (with params used to generate SPL header) to Kconfigs

- updated driver for NAND flash - tested both boot modes - mmc and nand

[SOLVED] Note 1: Bring back fpga char device

  • /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: Build php 5.6.40

  • 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: Entropy device hwrng

  • 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

Unsupported floating point instruction in kernel?

  • solution?:
Took arch/vfp/vfpmodule.c from kernel 4.19
The current was 4.14
It didn't work. Roll back and check which php call caused it?
  • TODO: keep an eye on this, because the real reason is not investigated

[SOLVED] Note 5: Bring up NAND OTP support

  • 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.

[SOLVED] Note 6: udev - unknown group 'kvm'

  • Problem:
[    5.817352] udevd[1478]: starting version 3.2.7
[    5.918028] udevd[1478]: specified group 'kvm' unknown
[    5.986364] udevd[1479]: starting eudev-3.2.7
[    6.142897] udevd[1479]: specified group 'kvm' unknown
  • Solution:
KVM == Kernel-based Virtual Machine. Remove for now (and maybe forever)
.
└── udev
    ├── eudev
    │   └── 50-udev-default.rules
    └── eudev_3.2.7.bbappend

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

[SOLVED] Note 7: Add back fixup for Atheros to updated ethernet driver

  • 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.

[SOLVED] Note 8: u-boot update

  • update u-boot
  • solution:
Updated to 2019.07 mainstream u-boot
- converted our *.h (with params used to generate SPL header) to Kconfigs
- updated driver for NAND flash - tested both boot modes - mmc and nand

- Note 9: test camogm

  • test camogm

- Note 10: test streamer

- Note 11: test AHCI driver
