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) | 2.6.28.y | 2.6.33.y | 2.6.34.y |
|---|---|---|---|---|
| IGEP v2 RC1 | 240mA | 550mA | ||
| IGEP v2 RC2 | 240mA | 460mA | ||
| IGEP v2 RC3 | 240mA | 550mA | ||
| IGEP SOC 3530 4G | 80mA | NA | 310mA | |
| IGEP SOC 3503 1G | 80mA | NA | 260mA |
Power measurements conditions:
- 1: Typical value when power-up with empty flash
MMC
I/O operations
#001 : Basic read/write operation
Category: performance
Description:
How to test:
The read tests were performed by running the following command:
$ time dd if=/dev/mmcblk0 of=/dev/null
The write tests were performed by running the following command:
$ time dd if=/dev/zero of=/dev/mmcblk0
The time used for the calculations was the time reported by dd.
Results:
| Test (SD 2GB) | 2.6.28.y | 2.6.33.y | 2.6.34.y |
|---|---|---|---|
| read | 2m 33s | ||
| write | 10m 13s |
