SDK2.3.0 FatFs sample for MIMXRT1050-EVK does not work

[masumoto]

Hi all,

I tried FatFS sample in SDK_2.3.0 for EVK-MIMXRT1050.

Console said:

FATFS example to demonstrate how to use FATFS with SD card.

Please insert a card into board.

Card inserted.

Then program stacked so it seems that

SD_PowerOnCard(g_sd.host.base, g_sd.usrParam.pwr) function failed.

This function just writes to a GPIO register

so I can't understand why this happened.

Any suggestions will be appreciated.

Kind regards,

Takeshi

Hi Takeshi Masumoto

Could you tried our latest SDK version (in this moments 2.6), those drivers were released for an old version of the RT1050. There are some differences and errors between the new and the old SDK version.

Hi Jorge,

Thank you for your answer.

For MIMXRT1050-EVK, SDK builder only show version 2.3.

Could you tell me where to find the newest SDK fot the board?

Kind regards,

Takeshi

Hi Takeshi

You can use the SDK for the MIMXRT1050-EVKB, for this SDK you can find the 2.6 version.

Hi Jorge,

Thank you! Your solution worked!

Now I can use FatFs.

However, PRINTF does not work...

Kind regards,

Hi Takeshi Masumoto

Please verify that you don't have enabled the semihosting option.

Hi Jorge,

It seems that semihosting does not work.

Anyway it is another topic so I will google this.

Tank you very much,
