SD card issue on S3 #6

Closed martinberlin closed 1 year ago

martinberlin commented 2 years ago

Still could not make it work with the SD card.

Maybe also bad hardware since I got the cheapest microSD from Aliexpress...

IO PINS: 

 ; setup the pins for the SDCard
 -DSD_CARD_PIN_NUM_CLK=GPIO_NUM_18
 -DSD_CARD_PIN_NUM_MOSI=GPIO_NUM_16
 -DSD_CARD_PIN_NUM_MISO=GPIO_NUM_14
 -DSD_CARD_PIN_NUM_CS=GPIO_NUM_9

Error in Serial

Looks like a hardware problem. SD cards works fine on my S3 cam board (where it is factory mounted).

Yes I tried it externally and also does not work. Probably cheap hardware with some level shifters prepared only for 5 V like arduino boards… Looking around later for a new microSD. Thanks!

The issue was that 32 GB does not work. With a 16 GB SD works correctly
