N1SDP : Ubuntu Loading Issues from SD Card.

While following the steps described in the getting started guide. 
We are stuck at a point where we are getting following error:

Booting `Install Ubuntu on N1SDP Platform'

UsbBootExecCmd: Success to Exec 0x0 Cmd (Result = 1)
UsbBootDetectMedia: UsbBootIsUnitReady (No Media)
error: disk `hd1,msdos2' not found.
error: you need to load the kernel first.\

We have tried multiple cards, with the Ubuntu flash image but we are getting the same error. 

Request you to guide on how to address this No Media issue that we are facing. 

  • Do you want to use the SDcard as the primary boot partition? 

    Or you already boot up the N1SDP into Linux OS, and then you insert the SDcard but SDcard is not detected correctly?

    Can you try a low speed SDcard class or high speed SDcard class that are different from the multiple cards you tested?

  • This issue is most likely due to multiple medias connected to the board while installing/booting Ubuntu. This is not recommended.

    Could you please confirm if the issue persists even with single media?
    * Remove all the attached USBs, SATA SSDs, sdcards(except the one on the board which has firmware binaries), etc
    * dd ubuntu.img on a new USB and connect to the board and reboot.
    * Let it install and reboot once it finishes installation.

    Also you mention "loading from SD Card", I am not sure how this is connected but we do not support (or test) booting from SD card. Could you please use a USB or SATA SSD to test?
  • Dear Ronan,

    Thanks for the resolution. 

    When I said we were using SD Card, we were using a SD Card mounted on a SDCard reader connected to the N1SDP using USB.
    I think the issue was that it had multiple slots for Micro SD, SD. And the default location where the boot image was expected was probably empty.

    After your suggestion we tried to load the boot image on an USB device, and we were able to boot and get the Linux prompt. 

    Thanks for the help!!.
