* QCA IPQ4028
* 256 MB of RAM
* 32 MB of SPI NOR flash (mx25l25635e)
* 128 MB of SPI NAND flash (gd5f1gq4ucy1g)
* 2T2R 2.4 GHz
- QCA4019 hw1.0 (SoC)
- uses AP-DK03 BDF from QCA4019/hw1.0/board-2.bin
* 2T2R 5 GHz
- QCA4019 hw1.0 (SoC)
- uses AP-DK03 BDF from QCA4019/hw1.0/board-2.bin
* 2 fully software controllable GPIO-LEDs
* 2 additional GPIO-LEDs which also affect the SIM card detection
* 1x button (reset)
* 1x GPIO buzzer
* 1x USB (xHCI)
* 1x NGFF (USB-only with Dual-SIM support, untested)
* TTL pins are on board (R124 is next to GND, then follows: RX, TX, VCC)
* 2x gigabit ethernet
- phy@mdio4:
+ Manual: Ethernet port 0
+ gmac0 (ethaddr) in original firmware
+ 802.3af POE (HV version)
+ 24v passive POE (LV version)
- phy@mdio3:
+ Manual: Ethernet port 1
+ gmac1 (eth1addr) in original firmware
* DC Jack connector
+ 24-56V (HV version)
+ 12-24V (LV version)
The SPI NAND flash isn't supported at the moment.
The bootloader has to be updated before OpenWrt is installed to fix a
reboot problem. The nor-ipq40xx-single.img from
https://downloads.compex.com.sg/?dir=uploads/QSDK/QCA-Reference/WPJ428/b170123-IPQ40xx-Reference-Firmware
has to be downloaded and the transfered in u-boot via TFTP
set ipaddr 192.168.1.11
set serverip 192.168.1.10
ping ${serverip}
tftpboot 0x84000000 nor-ipq40xx-single.img
imgaddr=0x84000000 && source $imgaddr:script
The sysupgrade image can be installed directly on flash using u-boot:
sf probe
tftpboot 0x84000000 openwrt-ipq40xx-compex_wpj428-squashfs-sysupgrade.bin
sf erase 0x00180000 +$filesize
sf write 0x84000000 0x00180000 $filesize
bootipq
The initramfs image can be started using
tftpboot 0x82000000 openwrt-ipq40xx-compex_wpj428-initramfs-fit-uImage.itb
set fdt_high 0x83000000
bootm 0x82000000
The used SIM card slot can be changed using
# slot 1 (also enables orange LED)
echo 1 > /sys/class/gpio/gpio3/value
# slot 2
echo 0 > /sys/class/gpio/gpio3/value
It can be checked whether a SIM card is inserted in the current slot and
the red LED is subsequently on via:
echo 2 > /sys/class/gpio/export
cat /sys/class/gpio/gpio2/value
