RTOS/PROCESSOR-SDK-AM65X: processor_sdk_rtos_am65xx_5_02_00_10 build time far longer than processor_sdk_rtos_am65xx_5_01_00_11

Thorsten,

Can you please indicate your host build environment.  Are you building in Windows or Linux.  Our observation from nightly builds using Yocto infrastructure shows all components in PRSDK 5.01 and PRSDK 5.02 took comparable amount of time with slightly higher time for the latest SDK.

Having said that, as an application developer, users should not have to gmake clean and build the entire SDK.  There are several libraries like CSL, driver libraries, OSAL that most customers would not need to rebuild unless there is a bug/patch they want to apply to those components.

Additionally, there are some flags that will help reduce build times significantly. 

Here are my notes from Processor SDK RTOS build and testing that might be useful to you to build some of the components and reduce build times:

PDK_build_notes.docx

The key is to do targeted builds for the platform you are working on, for the core you are working on. Hope this helps,

Regards,

Rahul

PS: Also, there is an effort to enable parallel make in the  that you can track using bug ID PRSDK-4574 and PRSDK-5247. This should help reduce the build times.

I am reposting the notes in the document so it is searchable for other community users. These notes will be added to Software developers guide soon. 

PRSDK PDK build notes:

The following steps can be used in a command shell to generate the CCS projects for PDK low level drivers. Users are expected to complete component discovery in CCS before using these steps.

Setup environment from root directory:

<SDK_INSTALL_PATH>\processor_sdk_rtos_am65xx_x_xx_xx_xx

setupenv.bat

Optional step: SDK contains prebuilt binaries for driver and CSL libraries so there is no need to rebuild the libraries but if you need to rebuild the libraries, you can do it using gmake utility using the following options.

gmake <target>_clean

gmake <target>

<target>: Refer to makefile in the pdk_am65xx_x_x_x\packages

all csl board emac fvid2 gpio i2c mcasp mmcsd nimu pm profiling pruss sciclient spi uart udma usb sbl sa osal can be used as <target>

This can take a while to build. To limit the build to A53 core, use the additional arguments as

gmake <target> LIMIT_BOARDS=am65xx_evm LIMIT_CORES=mpu1_0 <ARGUMENTS>

Caution: With DISABLE_RECURSE_DEPS=yes, you will run into link time errors if dependent component libraries are not built.

To apply the options globally, set the environment variables and then invoke the build

set LIMIT_BOARDS=am65xx_evm

set LIMIT_SOC=am65xx

set DISABLE_RECURSE_DEPS=yes     (Use only if dependent components are already built)

set BUILD_PROFILE=release    (Default setting is release)

Rahul
