2.1.6. Known Issues

This section contains the list of known issues at the time of making the release and any known workaround.

Record ID Board/s Component/s Summary Workaround
PRSDK-3482
CCS CCSV8.1: Intermittent issue not able to connect target while using DSS script Retry for connection failure in DSS script.
PRSDK-2336 am335x-evm, am437x-evm Power PM LLD test failing using CCS/JTAG
The debug versions of the PM apps are still functional. To build them:
From the top-level makefile in pdk.../packages folder run “make BUILD_PROFILE=debug pm” This will build the debug versions of the PM RTOS and measurement apps.
PRSDK-4725 am335x-ice, am437x-idk PDK PTP: ICSS-EMAC LLD Master Mode config does not sync with slave  
PRSDK-335 AM4X, k2g-evm High-Speed Drivers USB host MSC fails to re-enumerate Re-enumeration support for the case of device unplugged and plugged back currently fails for the example. Workaround is to avoid disconnecting drive while running example.
PRSDK-2892 am571x-idk, am572x-evm, am572x-idk PDK Incorrect A15 MMU configurations in default config file
Set MMU attribute to not executable for device memory
attrs0.noExecute = true; // Not executable
PRSDK-5179 am571x-idk, am572x-evm, am572x-idk, am574x-idk Control Drivers FATFS multi-partition fails to load file from windows formatted SD card with only Boot Record FATFS expects a valid primary partition. in sector 0. Use create-sdcard.sh provided in processor SDK to format the SDMMC card used for testing
PRSDK-1682 am571x-idk, am572x-idk Diagnostics Board diagnostics LCD Touchscreen test does not work with new version of LCD TSC For LCD/Display checkout example under VPS component could be used
PRSDK-5178 am571x-idk, am572x-idk, am574x-idk Board Support Uniflash: Host tool fails to load Flash Programmer, when Flash device is programmed
In case of AM5 platform, if flash device is programmed with a valid boot image, the board boots from flash as soon as powered on. After this, attempting to connect the board over JTAG will fail.
Workaround for this issue is to insert SD card without any valid boot image( to prevent booting from SD card), and power on the board. SD boot has boot sequence priority over Flash device. This will hold the board booting out of flash device.
PRSDK-4667 am572x-evm Demonstrations, Networking Image Processing Demo lock up on AM572x GP EVM Issue seen using 1Gig router on ETH0. Replace with 100Mbps
PRSDK-1975 am572x-evm Diagnostics timer_DiagExample_evmAM572x_arm7.out doesn’t work on ARM1 core Example can run on ARM Core 0
PRSDK-2166 am572x-idk High-Speed Drivers USB3.0 host problem with Sandisk Extreme USB3.0 stick Start the example without the USB plugged in. Once the example is up and waiting for USB stick, plug the USB stick in and it will enumerate properly.
PRSDK-3344 am572x-idk, am574x-idk Diagnostics icssEmac_TEST Diagnostics test not functional ICSS-EMAC LLD TI-RTOS example can be used for similar test.
PRSDK-5177 am574x-idk Board Support Uniflash: Flash programmer hangs when qspi flash is programmed with DDRECC enabled MLO
Issue will be seen while flashing with prebuilt MLO image. Workaround will be to rebuild MLO with DDRECC disabled and program the flash device.
Commands to rebuild MLO with DDRECC disabled:
cd $(PDK_INSTALL_PATH)tibootsbl
gmake all BOARD=idkAM574x SOC=AM574x BOOTMODE=qspi
PRSDK-3383 am574x-idk Diagnostics Diagnostics: lcdTouchscreen_TEST hangs Issue expected to be specific to TI EVM. For TI EVM, test need to be bypassed from the diagnostic menu.
PRSDK-4121 am654x-evm Boot make all fails for Windows due to missing openSSL package
- For Windows : Download and install Strawberry Perl. The Strawberry Perl installer automatically installs and sets up OpenSSL. | - For Linux : Execute the command “sudo apt-get install openssl” at the linux command prompt.ck | - Check if OpenSSL is installed by typing “openssl version” at the command prompt. |
PRSDK-4462 am654x-evm System IPC A53 ROV log won’t show correctly because of XDCtools bug Need to recompile examples/test with new XDC tool to resolve issues.
PRSDK-4706 am654x-evm, am654x-idk Boot SBL: MCU0 Boot in R5 Split Mode not supported in SBL
The SBL currently cannot reset the MCU1 subsystem to restart the cores in split mode. To workaround this, the MPU needs to reset the MCU1 sub-system
To configure the MCU1 susb-system in split mode, do the following.
a) Create a multi-core image with a MCU1_0 image, a MCU1_1 image and an MPU image.
b) The MPU1 image must contain code to reset the MCU sub-system. Refer the function sblTestResetMcu in sbl/example/k3MulticoreApp/sbl_amp_multicore.c for example code on how to reset the MCU subsystem
c) Before resetting the MCU, the MPU must wait for the SBL to boot MCU1_0
PRSDK-5080 am654x-evm, am654x-idk Board Support AM65xx diag failures on R5 core Can run failing test from A53 cores
PRSDK-4214 k2g-hsevm System create-sdcard script does not boot OOB Default generated App image is not signed follow the steps mentioned in User Guide of the Processor SDK Secdev Build and Install Guide to sign the app
PRSDK-4108 omapl138-lcdk High-Speed Drivers USB Audio: Lag when trying to adjust volume

2.3. Migration Guide

Overview

This page covers migration information for applications built on top of the last Processor SDK for RTOS release. |

Processor SDK RTOS 05.02.00

SBL

Migration: Image integration and memory map changes

Additional Details: Release supports optimized boot times for booting MCU1_0 core from OSPI flash. To reduce the size of the SBL, the system firmware image, which was earlier embedded in the SBL, is now a separate binary. The system firmware image can be found at <PDK>/packages/ti/drv/sciclient/soc/V0/sysfw.bin

For MMC/SD boot, if the steps followed in Creating bootable SD card in windows or Creating bootable SD card in Linux are used, no additional steps are need. If the SD card is being created manually, then the “sysfw.bin” file also needs to be copied into the root directory of the MMC SD card, along with “tiboot3.bin” and “app”

For OSPI boot, the flash offsets have changed. “sysfw.bin” needs to be programmed into OSPI flash at offset 0x40000 (new for this release), along with “sbl_ospi_img_mcu1_0_release.tiimage” at offset 0x0 (no change from previous release) and the “app” at offset 0xA0000 (was 0x80000 previous release). For details please refer Programming the OSPI flash

Applications that the SBL loads must co-exist with the SBL’s memory usage.In the application’s linker command file, care must be taken to not use the first 0x100 bytes of MCU1_0’s ATCM memory and SBL reserved memory from 0x41C00100 to 0x41C28000. If the applications violate the SBL memory usage, then apps that were working with the last release might not work any more, as the memory constraints are tighter. For details, refer the SBL Memory Utilization

PDK

Migration: AM65xx PDK component dependency on sciclient module.

Impact Scope: Applications will need to link to sciclient module library. No migration impact if application is already linking the library.

Additional Details: All application using PDK components on AM65xx platform will need to link sciclient library as components internally will be using sciclient API for PLL and interrupt configuration. In this release, requirement for application will be more mandated as more components are using common infrastructure.

DMSC firmware should be loaded onto Cortex-M4 core using SBL or CCS GEL script before calling the Board Init API with ‘BOARD_INIT_PLL’ flag.

Board

Migration: New APIs for EEPROM Board ID Information

Impact Scope: Applications using Board ID info APIs on AM65xx platform. No migration impact for existing applications and boards using version 1 API.

Additional Details: TI Board ID information format has been updated to new version on AM65xx. New board library APIs ‘Board_getIDInfo_v2’ and ‘Board_writeIDInfo_v2’ are added to support new Board ID information format. Old Board ID info APIs are still avaialble to retain the backward build compatibility but returns error when used on AM65xx platform.

FATFS

Migration: FATFS module in this release includes multipartition support and capability of detecting single vs multiple partitions run time.

Impact Scope: Limited to the case if user had used MS-DOS Floppy disk format for formatting the SD/eMMC memory. No impact if the SD/eMMC is formatted using the steps provided by Windows SD Card Creation Guide/ Linux SD Card Creation Guide

Additional Details: Partition entry information may be wrongly detected for the storage media formated to MS-DOS Floppy disk format. FATFS APIs fail to access the disk in this case.

Workaround: Format the storage media using the steps provided by Windows SD Card Creation Guide/ Linux SD Card Creation Guide in case this issue is observed.
