Most of our customers are using the dev kits in order to program their custom designs by using the on onboard JTAG, other than that i suppose that you can use a stand alone JTAG in order to program your 580 based PCB or you can use the UART ports. For JTAG the connections required are SWCLK, SWDIO and for uart RX/TX at the predefined pins that the 580 scans, also VBAT, GND and a VPP in case that you want to burn the OTP, and Smart Snippets ofcourse.
You can't program and debug the 580 through UART using keil, keil supports only JTAG interface. You can program the 580 using UART via the Smart Snippets and the UART Booter tool. You can use Smart Snippets in order to program the flash with the flash programmer tool.
我们通常使用FTDI芯片,我不知道if the module that you are using will work, if your pc can see it as a USB serial port, i suppose that smart snippets should see it as well in the UART option (not the UART/SPI option).

how do i set up Keil in order to program over UART (i have it connected that way)? Do i need an external tool for flash upload?

smartsnippets does not recognize the device on any com port. is there any way to force it to assign one?
Hi alkna13,
You need an FTDI chip in order for your pc to see the device as an available serial port.
Thanks MT_dialog
I am currently using the cy7c65211 USB Serial Bridge. Will that work? or must it be FTDI brand
