ProblemStatement: On EAP104, "fw_setenv" fails with the error "MTD erase error on /dev/mtd10: Invalid argument"
RootCause: uboot-envtools expects hex format for the number of sectors while the config file (/etc/fw_env.config) contains a decimal number format for the number of sectors. This leads to out-of-boundary size calculation within the function "environment_end()".
Solution: Update the scripts to write a hex value instead of a decimal value in the config file.
Reference for the expected format from the config file: Please check the function "get_config" in the file "fw_env.c", where the function uses sscanf to read the parameters from the config file.

Device specifications:
======================
* Qualcomm IPQ6000
* 256 MB of RAM
* 64 MB of SPI NOR flash
- 2x 28 MB available; but one of the 28 MB regions is the recovery image
* 2T2R 2.4 GHz Wi-Fi (11ax)
* 2T2R 5 GHz Wi-Fi (11ax)
* multi-color LED (controlled via red/green/blue GPIOs)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default))
* TTL pins are on board
* 2x ethernet
- eth0
+ 1000 Mbps Ethernet
+ used as LAN interface
- eth1
+ 1000 Mbps Ethernet
+ 802.3at POE
+ used as WAN interface
* 12 2A DC
* internal antennas
This device is not exported via a profile in TIP because there were
concerns about the 256MB limitations. But the actual OpenWrt support is
still added for interested parties.
Flashing instructions:
======================
Various methods can be used to install the actual image on the flash.
Two easy ones are:
ap51-flash
----------
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.
initramfs from TFTP
-------------------
The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):
setenv serverip 192.168.1.21
setenv ipaddr 192.168.1.1
setenv bootargs 'console=ttyMSM0,115200n8 rootfstype=squashfs,jffs2 board=PAX1800 root=31:10 mtdparts=spi32766.0:768k(0:SBL1),64k(0:MIBIB),1664k(0:QSEE),64k(0:DEVCFG),128k(0:RPM),64k(0:CDT),64k(0:APPSBLENV),640k(0:APPSBL),256k(0:ART),28672k(inactive),28672k(inactive2),64k(custom),64k(0:KEYS),2304k(0:WIFIFW)'
tftpboot <filename-of-initramfs-kernel>.bin && bootm
The actual sysupgrade image can then be transferred (on the LAN port) to the
device via
scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/
On the device, the sysupgrade must then be started using
sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

The toolchain path will not automatically be copied to OpenWrt. So the
build will still fail on recent Debian unstable version. Instead, it must
be applied during the setup.py process via the normal patch procedure.
