i.MX6 PCIe connection when JTAG debugger is used.

[satoshishimoda]

Hi community,

I want to confirm the connection of i.MX6 PCIe interface.

Please see the foot note of Table 2-21 in i.MX6 Hardware Development Guide (IMX6DQ6SDLHDG Rev.1).

It says "These supplies must remain powered if boundary scan test needs to be done".

Then, how about in a case that JTAG debugger is used even though JTAG boundary scan is not used?

Should I remain these supplies? or can I pull them down to GND?

Best Regards,

Hi Satoshi Shimoda,

The note doesn't impact JTAG debugger.

If there is no JTAG boundary scan required, you can follow both solutions.

Thanks!
