Compile and download using WICED SDK

Create the following make target if using Olimex ARM-USB-TINY-H

The command for downloading the scan example app in ...\apps\snip\scan

For Olimex ARM-USB-TINY-H

     snip.scan-CYW943907AEVAL1F JTAG=Olimex_ARM-USB-TINY-H download run

For Segger J-Link

     snip.scan- CYW943907AEVAL1F JTAG=jlink download run

If you need to debug add the debug flag

(debug configuration is default in SDK, if not present follow the steps here:

The command for downloading  and debugging the scan example app in ...\apps\snip\scan

For Olimex ARM-USB-TINY-H

     snip.scan- CYW943907AEVAL1F-debug JTAG=Olimex_ARM-USB-TINY-H download run

Note; If you are struggling to correctly download onto the CYW943907AEVAL1F with Segger JLINK, you may need to make the following changes:

1. Change jlink driver to libusb (internally, Zadig was used)

2. Add the line below to /tools/OpenOCD/jlink.cfg

reset_config trst_and_srst srst_push_pull

If you continue to have problems, then the openocd_log.txt file within the build directory contains more information on the failure.

How do you change the jlink driver to libusb?

Let me look into this with the apps team then get back to you.

I checked with vikr​ and he confirmed that on the Mac, there is no libusb or libwin32 and that this step is only needed for Windows.

Hi Guys,

Following the above steps. I am able to enter debugging using Segger j-link. The debugging come and stops at main. However now if i resume, the next breakpoint set by me in the code is not hit. Need help in resolving this issue.

Thanks & Regards,

Sandeep

1. How do you "change jlink driver to use libusb" for Windows
2. Will this affect my other IDEs that use JLINK for other processors
