2.3. Release Notes - 08_04_00¶
2.3.1. Introduction¶
This release notes provides important information that will assist you in using the PDK software package for the Jacinto family of devices. This document provides the product information and known issues that are specific to the PDK software package.
New features added / supported is listed below and defects fixed are highlighted in Fixed Issues. Also please check Upgrade and Compatibility for backward compatibility
2.3.2. What’s New¶
2.3.3. Upgrade and Compatibility¶
2.3.3.1. SBL¶
- We have modified the CPU IDs for all cores due to an increase in the number of cores in latest Jacinto device. E.g. CPU Id of mcu1_0 has been updated from 4 to 8.
- Hence user needs to generate the new app image with the current release to use the latest SBL.
- CPU IDs corresponding to each core can be found here: <pdk_base>/packages/ti/build/makerules/platform.mk.
2.3.3.2. SPI¶
- Previously SPI_open supported only 5 instances of McSPI(3 MCU instances and 2 Main Instances). Now separate APIs are implemented for McSPI and OSPI in order to support all the instances, user needs to use specific APIs as per the peripheral. E.g. User should use SPI_open() for McSPI and OSPI_open() for OSPI.
2.3.3.3. FreeRTOS¶
- On C66x CPU, interrupt router configurations for OS ticks is now handled in the OS_init() by FreeRTOS OSAL layer. Previously this configuration was done by application which is no longer needed.
2.3.4. Device Support¶
J721S2 GP SR 1.0 (BOARD=j721s2_evm)
Associated TIFS versions:
TIFS name J721S2 SR revision tifs.bin SR1.0 GP tifs-hs-enc.bin SR1.0 HS

2.3.10. Limitations¶
2.3.10.1. PDK¶
- PDK examples do not support SMP mode. Some of examples still support build in SMP mode but these binaries are not supported or validated.
- TI Clang compiler does not enable O3 optimization level and Thumb2 mode which were enabled by default with TI ARM CGT compiler. This has an impact on driver throughput. E.g. Ethernet performance has reduced by ~20% on J721S2
2.3.10.2. ENET¶
- lwIP stack integration doesn’t support checksum hardware-offload feature.
