I have in the past successfully integrated sdio with stm32f4/f7 microcontroller but cannot get it to work on. Sd cards that cannot perform data transfers in the specified range must discard themselves from further bus operations and go into inactive state2 I have an sd card with a standard beaglebone debian image Unfortunately, many usb sd card reader/writers don't support discard/trim I use this during production image writing on an embedded air quality sensor which i work on professionally. I have a problem with my ili9488 tft touch lcd module (arduino uno shield)
In another testprogram, i can serial.print() a c. I'm using a esp32 camplus ov5640 rev 1.2.1 (example) and cannot get the sd card to initialise I have stm32f407vet6 black board, cant connect the microsd card Im using onboard sd slot and a 32gb micro sd card by pny The card is okay and its already in fat32 formatted 7 it is possible to write raw binary data to an sd card
I'm using a microsd card in an embedded design The card is connected to a microcontroller using the spi interface It worked fine for all cards i've used before, but now my new card will not initi.
