Other Parts Discussed in Thread: OMAP-L137

The OBSEN field of CKEN and OBSEN registers are missing on quickStartOMAPL1x_rCSL for OMAPL137.

These fields are declared as reserved on the register structure.

Is there any problem on acessing this register´s fields?

Thaks,

Hi Gloria
That is a very old software package and not refreshed (it is posted as is)
The OBSEN fields were documented later and are supported - no issues accessing these register fields as documented in the TRM

Mukul,
Thank you!
By the way, do you know if there is a silicon errata for silicon revision 4?
SPRZ291I is just for 3.0, 2.1, 2.0, 1.1, and 1.0 silicon revision.

Gloria

Hello Gloria,

What is the full part number of the device you are using ?

There is no silicon revision 4.0 device available for OMAP-L137. It gone through up to revision 3.0 only.

Hello Senthil,

The full part number is OMAPL137DZKBD4, that means 4 device speed, but silicon revision 3.0.
Is there any documentation of diferences from speed 3 and speed 4?
Regards,
Gloria

Hello Gloria,

The device speed range 3 is 375 MHz and the speed range 4 is 456 MHz. The device datasheet covers this difference (refer Figure 6-1. Device nomenclature).
