Latest linux image for imx6

eugenephua — Mon, 02 Feb 2015 02:55:48 GMT

Hi there, i am using the imx6 Sabre Smart Devices Board. I saw there is a new linux binary demo file at : http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=RDIMX6SABREBRD&fpsp=1&tab=Design_Tools_Tab -> L3.10.53_1.1.0_iMX6QDLS_Bundle. I followed the manual i.MX Linux User's Guide 4.3.2 Copying the Full SD card image. However, when i try booting the board, it does not boot up...

This is the serial output:

Ahhh... The SD card reader on the board was not good... After plugging in and out a few times finally it booted!!! :smileyshocked:
