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:

(https://community.cypress.com/community/wiced-wifi/wiced-wifi-forums/blog/2014/05/09/creating-andor-...)

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

For Segger J-Link

     snip.scan- CYW943907AEVAL1F-debug JTAG=jlink 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?

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
