I'm looking for support and documentation on the HX3 ACA-Dock demo board. I've been able to successfully connect the Demo Board to several phones and tablets with differing results. The basic guide that is provided here:
http://www.cypress.com/file/145311/download
mentions that the Nexus 7 enters ACA-Dock mode when a 120kOhm RID_A resistor is present. However, based on this guide; the Demo Board does not use 120kOhm as one of the test RID_A values.
Is there any way to edit the algorithm on the PSOC4 so that different RID_A values can be simulated? I would like to verify this value for the Nexus 7, and test the same value for another tablet which is currently not entering ACA-Dock mode with the default RID_A values. The tablet in question does go into OTG mode but it will not charge in this state.

The guide explicitly says:
"Note The PSoC 4 firmware can be updated to support additional RID values as required."
How does one go about doing this?
