Development Hardware requirements

Hi,

We are going to developing some applications on DA14581 chip. I've gone through several documents and based on my understanding, the following devices are required in the debugging and programming process:

1.J-Link编程通过SW (JTAG调试器) interface
2. FT2232HL chip for USB to UART conversion
3. 6.8V power supply for programming the OTP after the design is finalized

Could you let us know if these are the minimum requirements? Do we need to have some other devices or can we remove some of the above items?

Thanks,
Hanfeng

Hi enormous,

Hi enormous,

Do you have a dev kit or you are going through the development by using a custom board. Yes those are enough to get you started. Also in case you have a dev kit you can download code to your custom board through the onboard jtag (in pro and basic kit).

Thanks MT_dialog

Note that JTAG is only needed

Note that JTAG is only needed for debugging. You can still program the chip on a production line with only UART communication.
And the other way: UART is not needed when developing, JTAG is usually enough, unless of course you want to use UART to communicate with some external peripheral.

Also, the devkit already has JTAG and UART connections to your computer via USB.

Hi Joacimwe,

Hi Joacimwe,

Thanks for the detailed explanation. Actually my basic dev kit has some issue on the UART connection to my computer. I've created another threadhttp://support.dialog-semiconductor.com/basic-dev-kit-usb-serial-driver-...for this issue. Wondering if you have any idea on this. Thanks.
