JTAG ACCESS IOMUX

[julianmp]

I would like to know how to acces the iomux and ocram through JTAG. At the moment, I was able to interact with the chain and set all the opcodes of the sjc. So the main thing now is know the steps to set iomux registers and write in ocram test programs ( like sdk scripts by usb port).

Hello,

    For software debugging JTAG_MOD should be pulled down.

If debugger can read / write data at an address - use Chapter 2 (Memory Maps)

of the i.MX6 S/DL Reference Manual to know the needed addresses. Chapter 37
[IOMUX Controller (IOMUXC)] contains information how to configure IOMUXC registers.

OCRAM may be used as usual memory. 

Have a great day,
Yuri

Basically I'm trying to dowload bare-metal code of the sdk into the imx6dl, in the readme file of IMX6 SDK Chapter 5.3 refers to Dowload with JTAG probe, but I don't know how to download it. I 'm using bus blaster debugger and I'm running with urjtag, Can I have any ideas?
