TMS320C6201 Silicon Errata

6 Silicon Revision 2.0 Known Design Exceptions to Functional Specifications

Program Fetch: Cache Modes Not Functional

Advisory 2.0.1

Revision(s) Affected: 2.0

Workaround: Use internal program memory in mapped mode.

Bootload: Boot from 16-Bit and 32-Bit Asynchronous ROMs Not Functional

Advisory 2.0.2

Revision(s) Affected: 2.0

Details: 16-bit-wide ROM mode and 32-bit-wide asynchronous mode work in run time without bugs.

The problem is only in boot. (Internal Reference Number 3088)

Workaround: Place all code in the lowest byte of the boot ROM.

DMA Channel 0 Split Mode Combined With autoinitialization Performs Improper

Reinitialization

Advisory 2.0.3

Revision(s) Affected: 2.0

Details: The source address (transmit read address) is reset too early when both split mode and

autoinitialization are enabled. The bug exists on DMA channel 0 only. (Internal Reference

Number 3481)

Workaround: Substitute one of the other channels for channel 0 when this configuration is desired.

DMA/Program Fetch: Cannot DMA into Program Memory From External

Advisory 2.0.4

Revision(s) Affected: 2.0

Details: Performing a DMA transfer into program memory while running from off-chip can cause invalid

program data to read by the CPU. (Internal Reference Number 2978)

Workaround: DMA into program memory only when running from internal program memory.
