OpenWRT - Install OpenWRT on Aruba AP-105

In this video, we will install OpenWRT on the Aruba AP-105 and configure it as an AP. For the Aruba AP-105, we can't just simply install the firmware via the TFTP because there is a checksum or signature verification of the firware by bootloader (or uBoot). We need to make a dump of the current rom, add the custom uBoot and write it back to the SPI NOR Flash chip of the AP-105 in order to install OpenWRT.
The the the Aruba AP-105 is using the SPI NOR Flash from Macronix. We will need a 16 pin test clip in order to establish the SPI connection between the SPI Flash to PC/Raspberry Pi.
