Hi,
We are trying to implement Challenge/Response Mechanism using Segger J-Link and VisualGDB on i.MX-RT1051
This mechanism is used to lock JTAG interface in manufacturing process to increase security of system. Authorized re-activation of JTAG interface possible in field-returned devices.
Description: nxp.com/docs/en/application-note/AN4686.pdf
NXP recommends Lauterbach TRACE32 debug tool. Segger J-Link is not supported yet.
Mechanism is very simple, and described in 2.1.2 Debug flow when Secure JTAG mode is enabled (see application note above).
Our question: how we can implement such Challenge/Response Mechanism using Segger J-Link?
