Kummi

Hi,

Just an confirmation about the errata Advisory 2.0.68.
Advisory 2.0.68: Continuous Writes From Cortex-A8 Occasionally Starve Other Requestors for DDR Bandwidth .

We would like to confirm if the above Errata is FIXED in the
latest Silicon Revision 2.1 ?

Best Regards
Kummi.

Hi Kummi,

I confirm this is fixed in 2.1

e2e.ti.com/.../993067
e2e.ti.com/.../666360

This fix will ensures A8 doesn't stall the other initiators from DDR access. The side effect of this is performance on A8 will degrade slightly for continuous memory writes. Without the silicon fix it will cause display to flicker if A8 is doing continuous memory access.
