Hello, im trying to share spi bus over sd and other device. But the problem is that card is not initializing.
I know about this page on documenation https://docs.espressif.com/projects/esp ... share.html but it's not enough helpfull at all.
I'm using esp_vfs_fat_sdspi_mount to initialize sd after second device, but it's not working.

You need to post a bunch more info for us to figure that out. What other device are you using, how are it and the sdcard connected, can you post your code, can you copy/paste the error log?
