<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head><body>Olimex has made a "arm-usb- tiny" jtag device thats around 50. Thats about as cheap as it gets for a "work with any manufacturer " jtag. If you are sticking to non commercial work, id go with the segger edu, i concur that they are rock solid. If you can find a cheap dev board for your brand of mcu with on board jtag, most can be converted to off board jtags, and thats ussualy your cheapest option.<br><br>-------- Original message --------<br>From: Christopher Svec via TriEmbed <triembed@triembed.org> <br>Date: 11/8/17 4:40 PM (GMT-05:00) <br>To: TriEmbed Discussion <triembed@triembed.org>, Alex Davis <alexd@matrixwide.com> <br>Subject: Re: [TriEmbed] Segger J-link or ??? <br><br><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"><div></div>
