HI, I’m Dani.
I want to test Sparkfun Apollo3 evb and JTAG connection.
so. i connect to EVB and JTAG , but It dose not work property.
I checked the connection and check the ‘heads up’ about EVB JTAG connection .
But, JTAG is not found the EVB.
Q1. Do I use the coin cell when i connect to JTAG and sparkfun evb?
Q2. Do I have to connect the VCC (JTAG and evb)?
I don’t know why It can’t be connected EVB and JTAG.
I am looking forward your answer. Thank you.
Best regards.
This is a little beyond what our Technical Support might be able to provide, but we will give it our best shot:
After searching online for similar cases, a few folks seem to have not hooked up the VREF cable - please ensure yours is?
Q1. Do I use the coin cell when i connect to JTAG and sparkfun evb? Perhaps try it and see?
Q2. Do I have to connect the VCC (JTAG and evb)? Also try it and experiment, if indicated in the guide/your use-case
Maybe this post/thread will set you down a path that helps: https://www.olimex.com/forum/index.php?topic=6039.0
