Difference between OMAP36XX/37XX and OMAP3630/3730 ?

Other Parts Discussed in Thread: DM3730

Hi,

I have two identical custom DM3730 boards.

One board shows this U-Boot message:

U-Boot 2010.03 (Mar 20 2012 - 14:00:39)
OMAP36XX/37XX-GP ES2.1, CPU-OPP2, L3-165MHz,
Die ID #516800029ff800000168300f1601a019

and the 2nd one:

U-Boot 2010.03 (Mar 20 2012 - 14:00:39)
OMAP3630/3730-GP ES2.1, CPU-OPP2, L3-165MHz,
Die ID #5bc800229ff80000016842c81703501b

Can anyone please tell me the difference between those two processors? Is one of this DM3730 an sample? Because of problems I'm interested in the exact revision of the two DM3730 processors.

Thanks and BR

    Hi Roland,

    As you can see from the both booting logs, both DM3730 processors have different Die IDs. The Die ID is something like identification code for each one processor. You can read more about Die ID and CONTROL_DIE_ID data registers in the TRM document chapter 1.5.2 Device Identification at the link below:

    http://www.ti.com/lit/ug/sprugn4r/sprugn4r.pdf

    For understanding of processing of the die ID, processor identification and printing the full processor description you can refer to: .../u-boot/cpu/arm_cortexa8/omap3/sys_info.c file and functions: dieid_num_r, identify_cpu and print_cpuinfo.

    BR
