Board revision codes in firmware

The following commandline will print a code to show which revision you have:

 cat /proc/cmdline | awk -v RS=" " -F= '/boardrev/ { print $2 }'

The related blog post provides source code to determine the board revision in different programming languages.

Code values are shown in the table below:

Code Model name New Features GPIO changes
0x2 Model B Rev 1, 256MB RAM (P2) JTAG pins, no mounting holes Pin3=GPIO0, Pin5=GPIO1, Pin13=GPIO21, I2C-0
0x3 Model B Rev 1, 256MB RAM no polyfuses, no mounting holes Pin3=GPIO0, Pin5=GPIO1, Pin13=GPIO21, I2C-0
0x4 (Sony) Model B Rev 2, 256MB RAM mounting holes Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5)
0x5 (Qisda)
0x6 (Egoman)
0x7 (Egoman) Model A, 256MB RAM mounting holes Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5)
0x8 (Sony)
0x9 (Qisda)
0xd (Egoman) Model B Rev 2, 512MB RAM mounting holes Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5)
0xe (Sony)
0xf (Qisda)
