Hello,
 

We have used both JTAG flash mode and EDL mode to flash the code, would like to know 

1) Which mode is preferred more and why?

2) Are there more failure cases in EDL mode while flashing then JTAG mode or is EDL mode relaible same as JTAG is?

Thank you,

 

Regards,

Akshaay

Both EDL and JTAG mode are reliable and preferred.
Since USB driver is not availble on QDN forum, we recommend customers to use JTAG instead of EDL mode.
