2.5. Release Notes - 08_04_00¶
2.5.1. Introduction¶

2.5.3. Upgrade and Compatibility¶
2.5.3.1. 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.
2.5.3.2. 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.
2.5.3.3. 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.
2.5.4. Device Support¶
J721E SR1.1, J721E-HS SR1.1 (BOARD=j721e_evm)
Associated TIFS versions:

|
[SPI] Transfer stalls when transfer length is not multiple of FIFO length in DMA mode |
McSPI |
07.02.00 |
J721E |
Cannot transfer data if data size is not multiple of FIFO length in DMA mode |

|
UDMA MCU NAVSS Channel Num 5 is not functional, when booting the application using the SBL bootloader. |
UDMA |
07.01.00 |
J721E |
Low Impact. UDMA MCU NAVSS Channel 5 can’t be used when booting the application using the SBL bootloader. |
Use any other channel. In the defaultBoardCfg Channel no. 5 is not used. The issue will be seen only when the boardcfg is updated to use channel 5. |
|
MCU/Main NAVSS UDMA memcpy from L2SRAM fails |
UDMA |
07.00.00 |
J721E |
Transfer works fine when source buffer, destination buffer and TRPD buffers are in L2SRAM. The issue happens only when the ring memory is in L2SRAM location |
Use ring memory from non-L2SRAM location |
|
Output mismatch when each region requiring 3 TRs |
VHWA |
01.00.00 |
J721E |
In multi-region mode with more then 3 TR per region can’t be used |

2.5.10. Limitations¶
2.5.10.1. 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 J721E
2.5.10.2. ENET¶
lwIP stack integration doesn’t support checksum hardware-offload feature.
