hi,
I am new to this world and I would like to learn ..
sorry for my english ..

I have a question to ask yourself,

I bought LPC1769 REV2, mounted on a prototype board, connected the SD, and everything works.

I have purchased from SmashTV,
1 = LPC KIT
4 = DIN KIT
2 = DOUT KIT
2 = MF NG KIT
I mount all the components, up to now no problem.

I connect the module on the board LPC1769 LPC KIT, I connect it to the PC connects with MIOS STUDIO and I get the “SD Card not found”
I turn off, insert the SD card, turn it on, but by this time I do not work anymore at all.

are formed in the SD Card standard 4 files but there is no communication with the PC.

if I mount the module again and the sd card into the card prototype re all works.

I checked the circuit over and over again but can not find solutions.

please let help me …

thank you ..

Hi,

 

I’ve no idea why there should be a problem with the SD card under these circumstances.

 

 

I turn off, insert the SD card, turn it on, but by this time I do not work anymore at all.

 

It isn’t required to turn off the core when you insert or exchange the SD Card.

 

What happens if you insert/remove it multiple times while the application is running.

Do you get additional error messages in the MIOS Terminal?

 

And what is the output of the “sdcard” command when you enter it into the terminal?

 

Best Regards, Thorsten.

hello TK. 

 

after installing “midibox_ng_v1_029” the problem is gone. 

 

thank you very much
