Services and Drivers

Two new APIs have been added

 An API to support the ADSP-BF609 Trigger Routing Unit (TRU)

 An API to support the ADSP-BF609 CRC DMA

Documentation for these APIs can be found the CrossCore® Embedded Studio 1.0.2 >

System Run-Time Documentation > System Services and Device Drivers > ADSP-

BF60x API Reference help section.

The USBD Device Driver now supports the ADSP-BF52x and ADSP-BF54x families in

addition to the previously supported ADSP-BF60x family.

Changed Functionality

L2_sram_uncached being used for parity error handler

The default parity error handler for the ADSP-BF60x family parts is now defined in

section L2_sram_uncached in order to follow the recommendation in the hardware

reference that such a handler should be defined in uncached L2 memory.

If you are using a custom LDF that does not have an INPUT_SECTION for this section,

you will need to add it. If you have modified your LDF to fill the memory section used by

L2_sram_uncached, called MEM_L2_SRAM_UNCACHED, you may need to make 134

bytes available for the handler to avoid link failures not seen previously when using

CCES 1.0.1.

Refer to the default non-generated ADSP-BF60x LDFs in <<CCES install

location>>/Blackfin/ldf for an example of how this might be done. (ref. TAR-50291)

2146x / 2147x / 2148x Loader Kernels

The ADSP-2146x / 2147x/ 2148x loader kernels were updated to workaround PLL

anomaly 15000020.

Symbol scrambling for ELF archives

Symbol scrambling for ELF archives using the elfar command's -s option now supports

two-character scrambling keys, so as to extend the number of available keys.

Additionally, the exclusion file for exempting symbols from scrambling can now contain

comment lines starting with a # character.
