# Flash Tool for Aruba AP-105
Tool to exchange Aruba AP-105 boot loader stored on a MX25L12835 flash chip with uboot for flashing OpenWRT with an RaspberryPi.
## Prepare
Requirements:
- RaspberryPi
- Programming clip SOIC16/SOP16 and cabling
- [Raspbian](https://www.raspberrypi.com/software/)
- [enabled SPI interface](https://codingworld.io/spi-aktivieren-am-raspberry-pi/)
- [`flashrom`](https://www.flashrom.org/Flashrom) tool
Configure SPI on the RaspberryPi:
```
sudo raspi-config
# Select Interfacing Options
# Select SPI
# Select Yes
# Select Ok
# Leave with finish or ESC
```
To install `flashrom`:
```
sudo apt-get install flashrom
```
Connect the AP105 Flash chip. The red status LED on AP105 must glow
```

```
## Usage
```
ap105-flash
```
The flash will be secured into files:
- `AP105--dump0.rom`
- `AP105--dump1.rom`
The `AP105--dump0.rom` will be patched with uboot binary `uboot.bin` and the file `AP105--patch.rom` will be created.
After a confirmation the patched file will be flashed to the device.
## Known problems
### Chip isn't detected by flashrom
- Check the wiring
- Ensure the RaspberryPi have enough power like a power supply with 5V/2A
- Ensure the red LED is illuminated on the AP105
- Reduce the SPI speed to 1000 kHz (default 16500 kHz)
```
SPEED=1000 ap105-flash
```
### flashrom fails during erase
- Check power supply
- Reduce the SPI speed like described above
