RATOC REX-WIFISD2 is a battery-powered wireless SD card reader with
- MT7620A + MT7610E
- 64MiB DDR2 SDRAM
- 16MiB SPI flash
- 2T2R 11b/g/n + 1T1R 11ac/a/n Wi-Fi
- 1x 10/100Mbps ethernet switch
- 1x SD card
- 1x USB 2.0
- 2x programmable LED
- 1x button
stock firmware is very similar to HooToo Tripmate travel routers. you
can do almost anything as a root user with telnet and/or shell script
(factory image or "EnterRouterMode.sh") on stock firmware.
"EnterRouterMode.sh" will be the easiest way to install. put the
following shell script into SD card (or USB storage) as
"EnterRouterMode.sh" with "kernel.bin" and "rootfs.bin" files.
----
#!/bin/sh
dir=`dirname $0`
mtd_write write ${dir}/kernel.bin Kernel_RootFS
mtd_write -r write ${dir}/rootfs.bin Rootfs
----
it will be run automatically when SD card is mounted on stock firmware.
TFTP can also be used to flash kernel and rootfs. it will be run by
press & hold RESET button while power on. (serverip=10.10.10.254)
you may use all partitions between "kernel" and "rootfs" as a single
"firmware" partition (please edit dts yourself), but "params" partition
should be kept if you want to restore stock firmware.
