How to find the Silicon Revision of your OMAP35x
Read back a 32 bit word from the CONTROL_IDCODE Register at address: 0x4830 A204
| Silicon Revision | 32-bit readback value |
|---|---|
| ES1.0 | 0x0B6D 602F |
| ES2.0 | 0x1B7A E02F |
| ES2.1 | 0x2B7A E02F |
| ES3.0 | 0x3B7A E02F |
| ES3.1 | 0x4B7A E02F |
Use the memory dump capability of u-boot:
U-Boot # md 0x4830A204 1 4830a204: 2b7ae02f /.z+
From the read back value: 2b7ae02f, you can see the revision of this OMAP35x corresponds to ES2.1
Power consumption
Power measurements taken over the operating conditions specified.
| Platform reference | Power-up (1) | kernel 2.6.28-3 (2) |
|---|---|---|
| IGEP v2 RC1 | 240mA | 550mA |
| IGEP v2 RC2 | 240mA | 460mA |
| IGEP v2 RC3 | 240mA | 550mA |
Power measurements conditions:
- 0: Typical value when power-up with empty flash
- 1: Typical value running kernel 2.6.28-3 and default rootfs (firmware v3.2.1-0)
