Recently I am trying to use nrf52840 to implement SPI slave on zephyr In Nordic's SPIS example, it will go to spis_event_handler when an interrupt occurs In spis_event_handler, judge whether the trans

Hi all, I would like to know the status of WINC1500 driver in zephyr. Is this fully tested? We are currently working on a product that uses Nordic's nRF52832 with WINC1500 over SPI. For our developmen

Good afternoon, I'm a zephyr newbie, trying to implement it into an IoT project! I'm aware that there is already a driver for the MX25 flash memory device in the nrf's dev kit, but I wasn't able to im

Instead of adding k_usleep(30), I changed the SPI clock from 210kHz to 406kHz for STM32F769. Then, the problems of A and B are gone. Still I have the problem of C. I receive 0x07 instead of 0x01. From

From what I checked: - A. 74 clocks stop with a change in CS without sufficient delay - B. CMD0 (0x40 0x00 0x00 0x00 0x00 0x94) fails to send 0x40... (instead send 0x20...) - C. CMD0 fails to receive

Thanks for the answer. You are right, the problem was solved implementing the fatfs_unmount function that you said. I made some tests and everything is ok. On the weekend I will create a PR.

Lucas, You're right, the unmount operation isn't implemented in the FAT fs_file_system_t struct. It should be possible to implement it easily, though. Something along the lines of: static int fatfs_un
