Flashing via ISSM


Lately I've been evaluating microprocessors for an upcoming product design and I can't help but wonder if I'm doing something incorrectly. I have what I consider a small application (approximately 30KB compiled), and the process of compiling & flashing this application using ISSM (on Windows 10) to the C1000 eval board takes upwards of an entire minute to complete. In comparison, I have an STM32 dev board compiling using IAR and the entire process of compiling & flashing completes in less than 10 seconds. I'd like to choose the C1000 (for various reasons), but waiting more than a minute to begin debug is frustrating, and I'm worried how this might scale as the app grows. Has anyone encountered this issue? Is there a rate or speed setting I'm missing?

Thanks folks,

Hi James,

Can you confirm whether you are compiling QMSI or Zephyr applications (Compiling Zephyr applications takes considerably longer on Windows).

Is it the compiling or Flashing that is taking time ? For me I see consistently < 10 secs to flash a 30kb application from ISSM on Windows 10
