Re: CM3 module crash after ejecting sd card

Hi all, Even without removing the sd-card I have had a complete freeze a couple of times. If I don't use the sd-card everything seems to be working fine up to now. Somehow I have the feeling the kind of glitch is the same as when you remove the sd-card. I tried the sd_debug parameter in the device-t...

Re: CM3 module crash after ejecting sd card

At the moment just some log data. Customer will use the card to exchange some files. So in the end there's always a possibility somebody ejects the card too early. The application software should give an error on the screen or something like that. Freezing is not an option for this design. That mean...

Re: CM3 module crash after ejecting sd card

I fully agree you should not remove the card during any operation at all. So certainly it's not a use case. Unfortunately the sd-card is free accessible just as in a laptop so people are able to remove the card.

Re: CM3 module crash after ejecting sd card

Correct. No reboot. Just freeze. No warning message or whatever in the console or log. I have to do a manual reboot to get it working again. Inserting removing the card is no issue. /var/log/syslog confirms. So only when I remove the card during the writing proces of a large file the CM3 freezes. If...

Re: CM3 module crash after ejecting sd card

Hi,

1. No error messages in /var/log/syslog
2. Nothing in the serial debug terminal. I'm using GPIO32/GPIO33. I have a LCD connected so the GPIO14/GPIO15 pins are in use.

Regards,

Chris

CM3 module crash after ejecting sd card

Hi all, I have a very annoying issue with the CM3 module which is used in a custom carrier board. After ejecting the external sd-card (SD1 interface) the complete module will crash. I've already removed the non-removable stuff from the devicetree. So I'm able to insert and remove the sd-card after t...
