New ContributorDear all,
I am using a Cyclone V SoC. Is there a way to set a default value for IOs configured in QSYS as LOAN IOs during power up (preloader and uboot)?
Thank you and best regards
Hi,
this solution mention on how to make the loan IO pins to 'tristate' instead of default value which is logic '1' during power up.

Regular ContributorHi,
I am Farabi who will be supporting your request.
Loaner IO will be driven to logic '1' during power up. Unfortunately, there is no feature to set these loaner IO pins to other state like other IO pins.
You can find details here: https://www.intel.com/content/www/us/en/support/programmable/articles/000079815.html

New ContributorThank you very much for your answer. I will try to implement the workaround. Can you tell me how to call sysmgr_pinmux_init()?
Thank you very much and best regards
New ContributorThanks again, the workaround works. I was able to set the appropriate GPLMUX register in the System Manager Module from the application to 0 to set them to LOAN IOs.

@JackAward Probably a good time to provide a chatgpt answer to a two-year-old thread.
