Hi I tried to change pinmuxes like you have but the issue still persists.
Reset is pulled high, so that is not causing the issue.
Since I have source code of the kernel which is build in image that works with other overlay, I can see that all options are included like in my kernel.
This is my waveform. Blue is CS line, and yellow is clock.
During error log it goes high for very short time, and clock goes high.
Then CS goes low, and high again. After going low clock is clocking something on MOSI line, and after that nothing visible on MISO line, and CS stays low.
Hi @benedict.hewson I suspect that driver is keeping CS1 low after MOSI transaction is finished, but dont know why. I dont have externall pull up on that pin.
Hi @benedict.hewson,
Thank you very much for your support!
I still was not able to solve the issue.
@RobertCNelson ,
Do you have anyinsights what is causing the “tpm_tis_spi: probe of SPI1.1 failed with error-110”?
This are my schematic parts where SLB9670 connections are visible.
Any suggestion will be highly appreciated.
Thank you all!
Regards
Hi @benedict.hewson ,
I believe that i experience issues that are resolved with this two patches. If tpm stays in reset stat during boot -110 error occurres.
https://lore.kernel.org/lkml/20230424062643.19392-1-shaopeijie@cestc.cn/T/
https://lore.kernel.org/lkml/1229fbc4-0abd-376e-a9d7-ccdd6d56c2ae@gmx.de/t/
But there is no kernel version available for BBB wirh this patches applied.
Best,
Nino
