i.MX6 Booting from NAND

madhusoodanabai — Tue, 16 Oct 2012 10:43:23 GMT

Hi,

We are using i.MX6 quad processor (PCIMX6Q6AVT10AA) in our design. We are trying to boot the processor from NAND (datasheet attached) & currently we are not able to achieve it. The iMX6 boot configuration pins' status & the schematics of NAND interface with processor are attached for reference.

With Regards,

A easy way to tell the boot configuration right or not is that to probe the nand bus, if the configuration is right, at least, some activty can be found on the bus. Then please check the page size, etc.

Hi Chongbin Fan,

I have probed the NAND bus & able to see pulses on NAND data lines, but booting is not happening.

I am using page size of 2 Kilo Bytes. Datasheet of the NAND chip used is attached with this mail.

Hi,

Do you have a way to test an 8Bit nand flash?, all as I know 16 bit are no longer supported in imx6 platform, and the RM system boot does not have how to configure the 16 bit option.

-ni.

After boot failure, please connect the OTG on the board to the PC, if a new HID device can be found, the ROM code enter serial download mode which mean some error occurred in the booting process.

Then please attach the board with any JTAG debugger, such as RV-ICE or Lauterbach and dump 0x907400, you should see your IVT header here if the NAND access is ok.

Hello,

Is there any pull up or pull down require between the iMX6 and the NAND flash ? is there somewhere in the documentation something about the NAND connection with the iMX6 ?

Thank you
