Red pitaya could not start

[wangfera]

I have got a Red Pitaya.I used 32GB micro SD card.I used Win32DiskImager to write the image into SD card.But it could not start.I get the starting information.It said that Unable to mount root fs on unknown-block.What's the problem?How can I solve it?

Hi, have you installed latest OS from: http://redpitaya.com/quick-start/ ? Do you have maybe another SD card to test?

Hi, have you installed latest OS from: http://redpitaya.com/quick-start/ ? Do you have maybe another SD card to test?

I have installed latest OS from: http://redpitaya.com/quick-start/.It also could not start and the output messege is same.I didn't use another SD card to test.Does the 32GB SD card is too large? What is suitable memory space？Is 8GB OK?

[Nils Roos]

I don't think that 32GB is too large, writing the image to the card makes it look as though there are 4GB available, no matter the actual capacity. 4GB is the minimum size that is required, so 8GB is ok, too.

From the look of your trace, I'd say either the card is defective or writing of the image was not complete - it takes quite some time to write the full image.
