Starting Linnux from SD card accompanied with the Zedboard

Ray Huang · December 2, 2017

Hello,

Some messages could not be displayed correctly as below when I boot Linux from the SD card accompanied with the Zedboard. Do you know how to fix it? Thanks.

Hi @Ray Huang,

Your 8GB with adapter should work just fine as long as the sd card is formatted to FAT32. Also just copy and past the contents of the sd_image onto the sd card and you should be good. I have attached a screen shot of the contents you need to copy.

thank you,

Jon

I think that some prohibited letters are used or there are some typo at line 0.68 and 0.69. So, it can't display correctly. I tried for several times with different setting at the terminal. Similar issue is happened at these lines. You can find a Zedboard and any accompanied SD card to check.

jpeyron · December 3, 2017

Hi @Ray Huang,

Can you attach more of the message to better see whats going on.

thank you,

Jon

jpeyron · December 11, 2017

Hi @Ray Huang,

Tomorrow is the soonest I can test the oob sd demo for the Zedboard. Sorry for the inconvenience.

thank you,

Jon

jpeyron · December 12, 2017

Hi @Ray Huang,

I ran the out of box demo on the zedboard without typo issues today.

I know that sometimes serial terminals can show weird characters. What serial terminal are you using? I would suggest tera term.

cheers,

Jon

Ray Huang · December 13, 2017

Hi Jon,

I'm using Tera Term ver. 4.96 in Windows 7 Pro. The issue still happened.

Ray Huang · December 13, 2017

Here is the attachment for screen shot with terminal version. Does it mean the original SD card has some issue? Thanks.

Ray Huang · December 13, 2017

Hi Jon,

After removing current Tera Term and install an older version, a similar issue still happened. Could you please teach me how to get a resource to reload related files to SD card? If you could help me, I can send the accompanied SD card to Digilent, too. Thanks.

jpeyron · December 13, 2017

Hi @Ray Huang,

What REV is your Zedboard? The OOB demo can be found on the resource center under Additional Resources. If you have an extra sd card please download the zip file and place the contents of the sd_image folder on the sd card which should be formatted to fat32. Do you still get the issue on lines 69 and 70? I have also reached out to our embedded linux engineer to see if they have any additional input.

cheers,

Jon

Ray Huang · December 14, 2017

Hi @jpeyron

My Zedboard is a new one with REV D. I bought it from Digi-key to save shipping cost. I'll try to reload the contents of the SD_image folder on a SD card. But, I'm not familiar with the process and will take some time. I have another 8GB empty MicroSD card with adapter which I bought from Digilent. Does it work to replace a 4GB SD card accompanied by Zedboard? Thanks.

Best regards,

Ray Huang
