[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
- Note 4: PHP causing 'unsupported FP instruction in kernel mode'
- php, what's that?

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
/var/state/camogm_cmd accepts only the first write - switch to polling? when switched to polling - when recording - buffer gets overflow?
[SOLVED] Note 10: test streamer
- test streamer
Streamer works
- Note 11: test AHCI driver
- test ahci driver
