Pb with SD card
by Desiderius from LinuxQuestions.org on (#4YZPC)
Hi all
I have just purchased an SDXC 64 Gb card formatted in exFAT.
I have tried it with Windows 10 : it is ok !
Same computer and same reader but with Slackware current :
- The SD card is not seen and of course not mounted
In /var/log/syslog I have found :
Feb 5 18:31:13 pegase kernel: [14134.137311] mmc0: error -123 whilst initialising SD card
Feb 5 18:31:15 pegase kernel: [14136.050156] mmc0: cannot verify signal voltage switch
Feb 5 18:32:11 pegase kernel: [14191.570449] mmc0: cannot verify signal voltage switch
Feb 5 18:39:37 pegase kernel: [14637.627027] mmc0: cannot verify signal voltage switch
What is this problem and how to fix it ?
