I wanted to share an issue using IAR and an I-Jet to program a Kinetis MCU for the first time.  In this case, it was a K70, but after working on it, the customer figured it out.


With the I-jet, initially they could not establish a connection with the two boards to program or debug.  The MCU was identified successfully over JTAG, but the reset sequence failed.  The JLink connected with no issue at all.  They also found that after the JLink had programmed the MCU, then they were able to re-program just fine with the I-Jet.


Then they played with a blank board that had not been touched yet.  And they found by changing the Reset option in IAR to Hardware, as shown below, the I-Jet was able to connect and program the blank board with no issue.  IAR had defaulted to this Reset setting to Custom.
