Ciao Øyvind, you are right; to support so many custom 0.1" pitch connectors, a universal cable/adapter it's good to have. Such cable is already available bundled with many commercial JTAG devices. I've just used google images to search "JTAG cable" getting pictures of Xilink adapter http://wikimart.tradeprince.com/detail/tradelead/1690721.html STLink http://www.aliexpress.com/product-fm-img/385045930-NEW-ST-LINK-STLINK-ST-LINK3-STM8-STM32-ARM-emulator-wholesalers.html http://strawberry-linux.com/images/st-link_2.jpg and many others. The links you propose, provide the complete set of tools to make them by yourself. I've home-made few of these cables, and I want to share the main issues I had. Please check carefully the single pin plastic housing http://www.pololu.com/catalog/product/1900 I've found that some manufacturer produce them with outer size a little bigger than 0.1". I remember around 2.7 mm instead of 0.1" = 2.54 mm. Such small difference is enough to prevent connecting them side-by-side. So, check carefully before buying . Second suggestion. On JTAG side, use a connector that cannot be plugged upside down. e.g. http://www.tycoelectronics.com/catalog/pn/en/102387-4?RQPN=102387-4&s_cid=SAM4 Sometimes I'm so focused at connecting each wire on the target side, that I mess up the other side. If the connector I propose is hard to find, there are other solutions that can achieve same result; e.g. a missing pin on the JTAG side (check the big picture of STLink) with corresponding filled hole on the cable. The connector manufacturer usually provides the proper plastic hole filler http://www.tycoelectronics.com/catalog/bin/TE.Connect?C=10075&M=PPROP&P=54760,86163&BML=&LG=1&PG=1&IDS=9901,85132,9900,43559,43560,9902,104836&N=7 Best Regards, Antonio Borneo _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
