Debugging methods of USB products (fx3, ccg3pa)

  Infineon USB product line , Mainly from the past Cypress Of FX3 and CCG3PA product , On this basis, we have expanded and subdivided the product series , For example FX3 Based on it, it is divided again CX3、HX3、SD3 etc. , This series mainly implements interfaces , such as USB2.0、USB3.2Gen1、USB3.2Gen2 etc. , alike CCG3 Then there was CCG4、CCG5、CCG6、CCG7 as well as PMG1 etc. , Some are integration DC-DC Some are new Masters MCU function , The main achievement is PD3.0、PD3.1 The charging interface , This is also the current hot spot , Namely C mouth +PD Charge .

FX3 product , The chip core is ARM926, Infineon offers SDK Sample development kit , Mainly used IDE yes EZ USB Suite, But in a hurry JTAG It is not very stable when debugging , Some functions are not accessible , The basic debugging method is to use UART printf log come out , That is the so-called blind tone .

 CCG3PA, Or say CYPD3171 chip , The chip core is CM0 processor , Can achieve Buck、Boost Charge and discharge , The voltage range can cover SPR The scope of the , That is to say 100W within , Maximum 20V*5A, The main debugging method of this chip is also mainly through UART Realization log Output mode . Infineon offers IDE yes PSoC Creator, because 3171 Itself is eager PSoC4 Designed on the basis of .

whether EZ USB suite still PSoC Creator, You can export the sample project to KEIL perhaps IAR The way , Achieve better debugging function .
