Texas Instruments ACX100/ACX111
The TI ACX100/ACX111 is a already somewhat outdated 802.11 wireless LAN chipset, which is based on a ARM7TDMI core. There is an open source project which develops a Linux kernel driver.
| Chip | ACX100 | ACX111 |
|---|---|---|
| TI name | TNETW1100 | TNETW1130 |
| standard | IEEE802.11b+ | IEE802.11g+ |
| speed | 22Mbps | 54Mbps |

JTAG Port
When taking apart a Level1 WBR-2401B router, I noticed that the used ACX100 CardBus-card has a 6-pin header.
As it turned out by try and error, it is connected to the JTAG pins of the ACX100 chip. Once it was clear that the first 2 pins are GND and VDD (+3.3V), I tried all combinations of the JTAG signals.
| Pin | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| signal | GND | VDD | TCK | TDI | TDO | TMS |
