I am working on to connect the JTAG to the mityarm board.
But having trouble how to proceed with project creation and connecting to target.
Do you have any procedure or example how to connect and flash the kernel to the... - RV 09:58 AM Software Development: RE: Flashing NAND from SD Card
- Hi Tim,
I have programmed as per the address mentioned above.
But during booting MLO always looks for u-boot at 0x40000 and environment variables at 0x80000. As the bootloader size is more than 256K it goes beyond the location 0x8...

things to be in

I could load bootloader to NAND and my boot log is as below. Flashed MLO at 0x0 and u-boot.img at 0x40000. u-boot image size is more than 256KB which will be written beyond the address 0x80000.

Do we have any answer on this.
I found one thing interesting from booting sequence of the board.
Below are the details on partitioning of NAND. Do we have to follow these adresses while flashing NAND? If so memory 0x260000... - MW 11:05 AM Software Development: RE: Usage of I2C1 to connect external peripheral
- The error you are seeing is from the I2C device not seeing the proper ACK response from the I2C slave device when it issues the request.
Can you get a scope on the I2C lines and set a trigger during either of the transactions above?

I have flashed as mentioned above.
But even now u-boot prompt is not appearing after booting from NAND.

Your uboot image is 373252 bytes long
you are only erasing/writing 0x40000, which is 262144 (256k)
try erasing 0x80000 and use the command
U-Boot# nand write.i 0x82000000 0x40000 ${filesize}
to write it.
cheers

Thanks for your reply.
I will try with these files.
What are the sys-boot options i have to set while connecting to JTAG?
Thanks,

Attached are both a gel file and a ccxml file that hopefully will get you going. The gel file has been used previously and should work for you with the MityARM-3359 SoM.

The EREMOTEIO error comes from drivers/i2c/busses/i2c-omap.c and is because there is no Ack from
bus request.
Unless I misunderstand what you are doing, I don't think you can just change the pin muxing around.
