AM261x MCU+ SDK: Release Notes 10.02.00

| AM261x MCU+ SDK 26.00.00 |

Release Notes 10.02.00

Attention
  1. Also refer to individual module pages for more details on each feature, unsupported features, important usage guidelines.
  2. There is a known issue of PMIC Watchdog resetting the SOC every 10 mins in CCS Gel flow. This has been fixed in SBL flow by disabling PMIC Watchdog using I2C interface. Use Flash SBL NULL if CCS Debug is needed or Add the same logic for PMIC Watchdog disable in application if CCS debug using Gel flow is mandatory.
  3. DFU Utils tool is not supported on Mac systems due to a build issue.
  4. Uniflash 9.1.0 does not support out of the box flashing of AM261x-LP E2 binaries. As a workaround, use Uniflash's custom flasher feature mentioned here Custom Flash Support. Out of box flashing support for E2 board will be available in the next Uniflash release.
  4. The default Stack size is 16KB and Heap size 32 KB for SDK examples. This can be adjusted as per application requirement through Memory Configurator in SysCfg or by updating Linker script in case of standalone applications.
  5. SDK will be migrated to support CCS Theia from next release (SDK 11.0) and the support for CCS Eclipse will be deprecated.
  6. There is a known issue that OSPI pins in SysCfg GUI are getting reset automatically during any module change. The workaround is that OSPI Pins should be locked after proper configuration according to the board Pinout.
  7. The default SysCfg linked to CCS is an older version and needs to updated to the SDK supported version mentioned below. Please follow steps mentioned in Check Packages as seen by CCS.
  8. CCS 12.8.1 doesn't support AM261x by default. Please follow the steps mentioned in Download, Install and Setup CCS to enable AM261x device support.

Note
  The examples will show usage of SW modules and APIs on a specific CPU instance and OS combination.
  Unless explicitly noted otherwise, the SW modules would work in both FreeRTOS and no-RTOS environment.
  Unless explicitly noted otherwise, the SW modules would work on any of the R5F's present on the SOC.

It is requested to bypass the SW check as well to enable the customer to use the ADC. Workaround : only applicable in the devices with forementioned conditions. 1. Go to the file source/sysconfig/drivers/.meta/soc_ctrl/templates/soc_ctrl_adc_config.c.xdt 2. Find line with DebugP_assert(SOC_getAdcReferenceStatus(`montior2AdcMap[monitor][0]`) == true); 3.Change it to //DebugP_assert(SOC_getAdcReferenceStatus(`montior2AdcMap[monitor][0]`) == true);

## Upgrade and Compatibility Information

### Flash Migration in AM261x-LP : E2 to E1

The AM261x-LP E2 has Macronix flash and the sdk supports E2 OOB. In order to migrate to E1 (ISSI flash), the following steps needs to be done -

1. Open the syscfg gui for the application
2. Navigate to the flash module and use LOAD from JSON function
3. Select the "IS25WX064" flash provided in the sdk path - "{MCU_PLUS_SDK_PATH}/source/sysconfig/board/.meta/flash"
4. Select 8d protocol and rebuild the application.

### How to run FOTA examples on AM261x-LP-E1 board

Here, to make FLSOPSKD Benchmark example work with AM261x-LP-E1 board, please

1. Removed the `RUN_XIP_IN_PARALLEL` macro.
2. Change `EXT_FLASH_ERASE_EXTOPCODE` value to 0x21.

### Changes in FLSOPSKD and FOTAAgent driver

These 2 drivers has been revamped from grounds up and there is an API compatibility break from previous release. On how to use the latest drivers please refer to FLSOPSKD and FOTA Agent.
