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¶
| ID | Description | Module | Supported Platforms |
|---|---|---|---|
| NA | NONE | NA | NA |
2.1.3. Upgrade and Compatibility¶
2.1.3.1. PDK¶
- Added new target, namely safertos_examples, to build all SafeRTOS examples supported by PDK.
- For Example:
make -sj custom_target BUILD_TARGET_LIST_ALL=safertos_examples BOARD=<board> BUILD_PROFILE_LIST_ALL=<list_of_build_profiles>
- For Example:
2.1.3.2. SafeRTOS¶
- SafeRTOS examples earlier named as test_task_switch_safertos and safertos_test_ut are now renamed as task_switch_safertos and unit_test_safertos respectively.
2.1.3.3. OSAL¶
For SafeRTOS, all tasks are created with FPU enabled.
clockfxn paramater for ClockP_create is updated from type ‘void*’ to function pointer of type ClockP_FxnCallback
void (*ClockP_FxnCallback)(void *args);
2.1.3.4. RTOS¶
- C7X support files such as boot.c, Startup.c, Cache.c, etc, are moved to the CSL layer. They were earlier part of the respective RTOS portable layer.
2.1.3.5. OSPI¶
- A New parameter “opMode” is added to CSL_ospiConfigPhyDLL() API. This lets user to configure Phy to operate in either master mode or bypass mode.

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 J721S2
- The PMU counter overflow is not handled in Baremetal for use of CycleprofilerP APIs or the TimerP_getTimeInUsecs API.
- Applications can periodically use the CycleprofilerP_refreshCounter to check overflow and refresh the higher bits of the PMU counter.
2.1.10.2. ENET¶
- Scatter-gather functionality is currently supported only for packet transmission.
2.1.10.3. SafeRTOS¶
- OSAL APIs namely, HwiP_disable and HwiP_restore can only be called from a privileged mode. These APIs will give an assertion error for an unprivileged context.
- When snprintf is interrupted by an ISR, C7X core may crash while returning from the ISR. - As a workaround, snprintf can be protected with Hwip_disable() and HwiP_restore() to disable the interrupts.
