sample fat_fs

[TF mulder]

Hi,

I'm trying the  sample fat_fs  on the nRF5340 DK

1) It does build, but there is awarning

CMake Warning at D:\nRfConnect\v1.8.0\zephyr\CMakeLists.txt:722 (message):
No SOURCES given to Zephyr library: drivers__disk

2) looked with the debugger: in the main() it reaches the  LOG_ERR("Storage init ERROR!");

void main(void)

if (disk_access_init(disk_pdrv) != 0) {

LOG_ERR("Storage init ERROR!");

 

Could you please comment on the above 2 points ?

What steps should i make to have a SD-card running,  is using sample fat_fs the way to go ?

Best Regards,

Theo

Hi Simon,

Again nothing helps.., i now looked on a oscilloscope to the signals.., there is nothing there, (as if the GPIO-pins are just not cofigured)..

Where can i check/see the true configurations of the pins?

And ofcouse:

there is still the warning of my original question:

1) It does build, but there is awarning

CMake Warning at D:\nRfConnect\v1.8.0\zephyr\CMakeLists.txt:722 (message):
No SOURCES given to Zephyr library: drivers__disk

Looking forward to your answer..

Best Regards,

Hmm.. I'm sorry it's that much hassle getting it to work

I will take a deep dive next week and see if I can get to the bottom of it

Best regards,

Simon

Hi Simon,

Yes, please do so, ...much appreciated !!

One point i noticed:  in the Device Tree/ GPIO  there i could not find the  cs-gpios, while the 3-Spi signals can be seen in that list.

Im looking forward, to your deep-dive result.

Best Regards,

Theo

Okay, I took a deep dive, but before I add a lot of explanations and what could possibly be the cause, could you test one quick thing? Add these two configs to the file zephyr/samples/subsys/fs/fat_fs/prj.conf.

I think the warning "No SOURCES given to Zephyr library: drivers__disk" will go away when setting CONFIG_DISK_DRIVER_SDMMC=y

Check the file zephyr/samples/subsys/fs/fat_fs/build/zephyr/.config and make these two configs are present and that CONFIG_SDMMC_VOLUME_NAME (this should get enabled automatically when enabling CONFIG_DISK_DRIVER_SDMMC) is equal to "SD" (or whatever disk_pdrv is set equal to).

If it still doesn't work, please get back to me

Hi Simon,

i used:  'create new aplication from sample', 'freestanding'

and put in the directory D:\Projects\Nordic_Semi\nRF5340DK\MyApps\fat_fs

D:\Projects\Nordic_Semi\nRF5340DK\MyApps\fat_fs\prj.conf  contains now:

CONFIG_DISK_ACCESS=y

CONFIG_LOG=y

CONFIG_FILE_SYSTEM=y

CONFIG_FAT_FILESYSTEM_ELM=y

CONFIG_PRINTK=y

CONFIG_MAIN_STACK_SIZE=2048

CONFIG_DISK_DRIVER_SDMMC=y

CONFIG_SPI=y

saved all, and did a prestine build:

this is still there:  

CMake Warning at D:\nRfConnect\v1.9.0\zephyr\CMakeLists.txt:764 (message):
No SOURCES given to Zephyr library: drivers__disk

and in the file  D:\Projects\Nordic_Semi\nRF5340DK\MyApps\fat_fs\build\zephyr\  .conf

there is indeed:

CONFIG_SDMMC_VOLUME_NAME="SD"

Best Regards,

Theo

PS: i will go and check if i get signals ??
