SD CARD FAILS ON CALL FMOUNT STM32F107

Question asked by paveglio.giovani.002 on Aug 4, 2017

I am having strange problem on some boards, we use stm32f107, it was developed 3 firmware, the first one to check if flash sector of application firmware need update, second one to erase flash of application firmware and read from a SD CARD bin file to write on flash, most are working accordingly, but on others when the firmware responsable for write flash get executed when I call fmount it returns fsmediaerror.

 

I tried format sd card on FAT16 and FAT32 the result is the same, tried change sd card same results.

 

I forgot that we are using pins PC10, PC11 e PC12, PA4 of SPI3.

 

I would be so grateful if anyone could help me.
