Does the JTAG Reference EE-68 Apply to the Newer Processors?

No, the EE-68 application note describing the ADI-recommended JTAG circuitry applies to all of ADI's processor portfolio up to and including the ADSP-BF60x family of dual-core Blackfin processors.

Beginning with the ADSP-BF70x Blackfin+ processors and carried forward to the recently announced ADSP-2158x/SC58x dual-core SHARC+ processors, the debug unit infrastructure block was changed to also support ARM technology. As such, an equivalent application note is currently being developed in support of these and future devices.

  • This post says the EE-68 document does not apply to the newer processors. Working on a design with SC587 now, and page 24 of its data sheet still references EE-68. The latest version on ADI's website of EE-68 is dated 2008, so it hasn't been updated. There are still obvious differences between EE-68 and the pins available on the SC587. 

    Anyone know more about the plans for ADI to update EE-68, if ever? Currently having difficulty getting boundary scan to work with the JTAG port on SC587, and having ADI point to incorrect documentation in response isn't helping.
