PROCESSOR-SDK-AM62X: SDK Build PC Requirement

Part Number: PROCESSOR-SDK-AM62X

Hi PSDK Team

Can you please specify the minimum requirement for Yocto SDK Building with PSDK 9.0.0.3 latest?

I'm unable to build Yocto SDK completely even in tisdk-base.image. 

My laptop has 8GB RAM, 16~32GB SWAP, 500GB SSD and (native) Ubuntu 22.x LTS.(not VMware) 

The terminal window is suddendly closed during the building after several hours. and sometimes I could not resolve gcc compilation due to link errors. 

My customers have failed from Graphics. Vulkan......related recipe.  

Regards, 

Jack

    Hi Jack,

    with SDK v9.0 the requirements for the build machine have become much larger it seems. I would recommend a machine with at least 32GB of RAM (better 64GB) configured with an equal amount of swap space, and a very large SDD (like, at least 1TB).

    Note that you can dial down the requirements some by editing the conf/local.conf file section shown below and turn down the number of parallel bitbake and make threads:

    #
# Parallelism Options
#
# These two options control how much parallelism BitBake should use. The first
# option determines how many tasks bitbake should run in parallel:
#
# BB_NUMBER_THREADS ?= "1"
#
# The second option controls how many processes make should run in parallel when
# running compile tasks:
#
# PARALLEL_MAKE ?= "-j 1"
#
# For a quad-core machine, BB_NUMBER_THREADS = "4", PARALLEL_MAKE = "-j 4" would
# be appropriate for example
#
# NOTE: By default, bitbake will choose the number of processeors on your host
# so you should not need to set this unless you are wanting to lower the number
# allowed.
#

    Especially modifying BB_NUMBER_THREADS is very impactful. Try setting it to 8 (or even 4) while removing the leading comment character (`#`) to activate the definition.
