2.1. Release Notes - 10_01_00¶
2.1.1. 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
2.1.2. What’s New¶
2.1.3. Upgrade and Compatibility¶
2.1.3.1. ENET¶
The infinite wait for SGMII MAC-2-MAC is removed, linked will be polled in CPSW_periodic_tick task. This affects MAC loopback as well. Examples on MAC loopback also needs to poll now for link status instead of bypassing the polling on assumption of link to be always true.
2.1.4. Device Support¶
J742S2-HS-FS SR1.0 (BOARD=j742s2_evm)
Associated TIFS versions:

2.1.9. Known Issues¶
2.1.10. Limitations¶
2.1.10.1. 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 J742S2
When running tests using sbl_cust_img_hs or sbl_boot_perf_cust_img_hs, users should ensure that the SBL libraries (sbl_lib_cust_hs or sbl_boot_perf_lib_cust_hs) are rebuilt, followed by necessary binaries. This step is important to prevent potential issues caused by simultaneous library builds in the packaged SDK.
2.1.10.2. ENET¶
Scatter-gather functionality is currently supported only for packet transmission.
gPTP stack is supported only in FreeRTOS.
