IMX6 boot problem

[srinivasaporam]

Hi,

we have got customized board based on IMX6 Dual processor. Now when we have deployed linux image to the SD card and powering on the board, then nothing is happening ( no display is shown) ( monitor is connected to board through HDMI)

When we keep the same sd card to another evaluation board, then it is booting. Now to trace out the problem:

how i can confirm the processor trying to read/boot from the sd card, which happening but there is problem with the HDMI.

or

SD card reading is not happening.

how trace down where the problem is . when i connect the board to my Ubuntu host system through USB-OTG and run the command $lsusb

iam getting following message:

and one more query, our board has got: MCIMX6D5EYM10AC, but why is it getting detected as:

Freescale Semiconductor, Inc. i.MX6Q SystemOnChip in RecoveryMode

HI Srinivasa

seems board falls to serial serial downloader,

in this mode in host computer device manager one

could see usb device:

MX6D vid="15A2" pid="0061"

MX6Q vid="15A2" pid="0054"

It may be recommended to check boot settings and Chapter 8

Hi,

Our board has got MCIMX6D5EYM10AC chip which should be dual core since it has 6D not 6Q. But when we are connecting the board to host (Ubuntu) system and running lsusb command , then output is :

Bus 001 Device 006: ID 0bda:58c2 Realtek Semiconductor Corp.

Bus 001 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller

Bus 001 Device 007: ID 0cf3:0036 Atheros Communications, Inc.

Bus 001 Device 003: ID 046d:c077 Logitech, Inc.

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

If we see the output carefully it is detected as "Bus 001 Device 014: ID 15a2:0054 Freescale Semiconductor, Inc. i.MX6Q SystemOnChip in RecoveryMode" which Quad. is this normal??? any problem???? how to get confirmed which is correct one???
