Timeout on sdcard after sdcard-power-cycle
basvs opened this issue · 5 comments
Current order:
- enable power to sdcard
- mount sdcard with esp_vfs_fat_sdmmc_mount()
- read/write files
- unmount sdcard with esp_vfs_fat_sdmmc_unmount()
- disable power to sdcard
When doing a 2nd mount (power-on, mount, unmount, power-off, power-on, mount), the initialization fails with a timeout. It sounds like I have to initialize something extra.

More testing:
- re-insert sdcard → sdcard works
- restarting 'make monitor' (doing a soft reboot) → sdcard works
Can not reproduce . .
Still reproducible here. I guess your sdcard brand is better. :-)
But I created a fix. Patch is on its way.
