Building and Installing OpenWrt on the Gateworks Laguna Family
Customers may choose to compile their own firmware or use our prebuilt binaries prebuilt-binaries.
Please refer here for instructions on building OpenWrt for the Gateworks products.
There are two distinct sets of products in the Laguna family and instructions on flashing firmware over Serial/ENET differs depending on which you have:
- NOR Flash - GW2387, GW2388, GW2391
- SPI Flash - GW2380, GW2382, GW2383 (small form-factor boards)
OpenWrt Release Information
The following OpenWrt branches support the Laguna Family:

If you prefer to grab the source code and build images yourself, please refer to this page for instructions.
Installing Firmware on a Laguna board via JTAG - Best Option
See JTAG firmware install here: jtag_instructions
Installing Firmware on a Laguna board via Serial/ENET
NOR Flash (GW2387, GW2388, GW2391)
If you have a JTAG programmer it may be easier to install firmware this way as it does not require ethernet, or a tftp server: See above
To install firmware to a NOR Flash Laguna board using Serial/ENET once your kernel/rootfs are on a network attached tftpserver TFTP Instructions (Customer must setup TFTP server) do the following:
- Connect your target board to your network, set ipaddress and serverip in uboot:
Laguna> setenv ipaddr 192.168.1.1 Laguna> setenv serverip 192.168.1.146
- boot the board and hit any key to break out of the default bootscript and get a U-Boot prompt
- Set ipaddr/serverip to something that makes sense for your local network
- Erase the entire flash (once executed the linux fs and kernel will be lost):
Laguna> erase 0x10060000 0x10ffffff
- for 16MB flash use 'erase 0x10060000 0x10ffffff' (default flash size)
- for 32MB flash use 'erase 0x10060000 0x21ffffff'
- for 64MB flash use 'erase 0x10060000 0x23ffffff'
- Copy Linux kernel and root filesystem to board:
- if you are using our 13.06 or later BSP the kernel and rootfs are combined into a single image:
Laguna> tftpboot 0x00800000 laguna/openwrt-cns3xxx-squashfs_laguna_nor.bin Laguna> cp.b 0x00800000 0x10060000 $(filesize)
- if you are using an older BSP that has only a separate kernel (openwrt-cns3xxx-uImage) and root filesystem (openwrt-cns3xxx-squashfs.img) use:
Laguna> tftpboot 0x00800000 laguna/openwrt-cns3xxx-uImage Laguna> cp.b 0x00800000 0x10060000 $(filesize) Laguna> tftpboot 0x00800000 laguna/openwrt-cns3xxx-squashfs.img Laguna> cp.b 0x00800000 0x10260000 $(filesize)
- if you are using our 13.06 or later BSP the kernel and rootfs are combined into a single image:
- Boot into Linux:
Laguna> boot
If the bootloader environment was modified you may want to erase the u-boot env flash section to set the board back to factory defaults. This can be don by the following:
Laguna> protect off 0x10040000 +0x20000 Laguna> erase 0x10040000 +0x20000 Laguna> reset

- boot the board and hit any key to break out of the default bootscript and get a U-Boot prompt
- Set ipaddr/serverip to something that makes sense for your local network
- Erase what is on the board currently (once executed the linux fs and kernel will be lost):
Laguna> erase 0x60080000 0x60ffffff
- for 4MB flash use 'erase 0x60080000 0x603fffff'
- for 16MB flash use 'erase 0x60080000 0x60ffffff' (default flash size)
- for 32MB flash use 'erase 0x60080000 0x61ffffff'
- Copy Linux kernel and root filesystem to board:
- if you are using our 13.06 or later BSP the kernel and rootfs are combined into a single image:

- if you are using our 13.06 or later BSP the kernel and rootfs are combined into a single image:
- Boot into Linux:
Laguna> boot
If the bootloader environment was modified you may want to erase the u-boot env flash section to set the board back to factory defaults. This can be done by the following:
Laguna> protect off 0x60040000 +0x40000 Laguna> erase 0x60040000 +0x40000 Laguna> reset
Information
You will also find tools to use all peripherals on the board such as the following:
- GPS (gpsd)
- uSD (fdisk, mke2fs, etc)
- SATA (fdisk, mke2fs, etc)
- RTC (hwclock)
- HWMON (sysfs)
- LED's (sysfs)
- USB (kmod-usb-storage, kmod-serial, etc)
- Serial (built-in)
