J721EXCPXEVM: building SBL without all examples only for a single board

Hi,

Simon Huelck said:

How is it possible to do a SBL only build ?

You need to build SBL with boot media like MMCSD, EMMC, UART for booting the device with your applications.

Simon Huelck said:

Can you describe what BUILD_PROFILE, BOARD and SOC defines are doing ? 

BUILD_PROFILE will define whether build is release or debug, by default it will be release.

BOARD & SOC defines building for which TI SOCs. like j721e_evm, j721s2_evm, j784s4_evm..

Hi,

- can you make an example for sbl for ospi, to only compile that to speed up ?

- can you point me to the related documentation ?

regards,

Simon

Hi,

Please go through SBL User Guide for PDK Documentation for more details.

Please refer to SDK Documentation for using SBL with OSPI.

Do you talk about this here in directory packages/ti/build ?

• make sbl_ospi_img SOC=<soc_name> BOARD=<board_name> CORE=mcu1_0 -sj

im facing the following issue, ccs 930 is used on windows 11

C:\ti\ti-processor-sdk-rtos-j721e-evm-10_00_00_05\pdk_jacinto_10_00_00_27\packages\ti\build>gmake sbl_ospi_img SOC=J721e BOARD=j721e_evm CORE=mcu1_0 -sj

found a typo (big J instead of small ), but now it complains here

gmake[1]: *** [mcu1_0] Error 2
makefile:328: recipe for target 'sbl_ospi_img' failed
gmake: *** [sbl_ospi_img] Error 2

with 2 step approach im able to complete it on windows:

1. gmake pdk_libs SOC=j721e BOARD=j721e_evm CORE=mcu1_0 -sj

2. gmake sbl_ospi_img SOC=j721e BOARD=j721e_evm CORE=mcu1_0 -sj

i do get warnings on missing awk tool in ccs. whats the reason that windows isnt supported ?

how is it possible to just "clean" the sbl , to avoid rebuilding the PDK. i just modified a source file and its not recognized by make
