I've been trying to to get the external (offboard) SD card working with my MOD54415 and I was having some trouble, so I've eliminated as many variables as possible and this is what I've got.

I have installed a fresh copy of the development tools 2.9.3 and I'm only using the example programs MOD5441X/EFFS-MULTIPLE-MMC and StandardStack/EFFS/EFFS-Performance. These were tested on a MOD54415 in a MOD-DEV-70 board.

The Multiple MMC example is able to read the onboard SD card just fine, but the offboard one shows up as not formatted.

Code: Select all

***************Off board flash
FAT mount to  failed: F_ERR_NOTFORMATTED
drive change failed: F_ERR_INVALIDDRIVE
Unmounting card

*** Error in f_delvolume(): F_ERR_INVALIDDRIVE

I know the SD card is formatted because I can read it fine on my computer and also in an old MOD5282 application I had laying around.

So I loaded up the Performance example to try to format the card anyways and the format call returns "invalid sector".

Code: Select all

Am I missing something obvious here?

What is the version number of your Mod-dev70
Have you installed JP4?

Posted: **Thu Oct 29, 2020 8:08 am**

MOD-DEV-70 Rev 1.93
JP4 is installed (what does that do?)

It connects the Write protect sense to the device...
So still no change in behavior???

No, JP4 was already installed the whole time. I just ran a test without JP4 and it then said it was write protected. Then I put JP4 back on and got the not formatted error again.

Thanks for that additional information. Can you please let me know the revision number on your MOD54415?

Posted: **Thu Oct 29, 2020 1:34 pm**

MOD54415 Rev 1.9

Hello,

I'm unable to reproduce the issue. Can you try the attached image file and let me know if you see any errors.

Posted: **Thu Oct 29, 2020 6:13 pm**

That app should be run with just the sd card plugged into the mod-dev-70, no card in the 54415 microSD slot

Running the program you provided seems to have the same results, so if that program worked for you then there must be something off with my hardware. I'll see if I can scrounge up a totally different dev board, processor, and SD card and try again.
