spi_fatfs.c incompatible with freertos?

[stantonious]

Hello - We're looking to access the sd card via spi_fatfs (similar to allon_sensor_tflm_fatfs) while use the freertos OS. It appears all of the sample spi_fatfs.c are using the eventlibrary, and are incompatible. While porting over spi_fatfs.c, the dp_task timesout trying to acquire with the following output

sensor_type: 15
OV5647 on by app done
g_cursensorstream: 0
os_app_dplib_cb event=-76
send to dp task 0x11c
os_app_dplib_cb event=-77
send to dp task 0x11e
dp_recv_msg_event=0x11c
dp_recv_msg_event=0x11e
main_recv_msg=0x203
main_recv_msg.msg_data=0x11c fail
main_recv_msg=0x203
main_recv_msg.msg_data=0x11e fail

Is there an example spi_fatfs that uses freertos?

Thanks!

Hi @stantonious,

We don't have this example, we'll need some time to port it.

Hi @stantonious,

We've added fatfs support for the allon_sensor_tflm_freertos application.
You can enable FATFS support by setting SUPPORT_FATFS=1.

EPII_CM55M_APP_S/app/scenario_app/allon_sensor_tflm_freertos/common_config.h.
#define SUPPORT_FATFS 1 // 0 : send images via SPI, 1 : save images to SD card
