14.2 Update using JTAG

Using this interface option allows performing a fail-safe ﬁrmware update even in case of a

broken ﬁrmware or misconﬁguration. The user needs hardware and software tools to be

able to perform this procedure. In detail those are:

• Flash adapter for Cortex M µC supporting TI CC1310 (Not every adapter supports the

used connection methods). Recommended adapters are: "Segger J-Flash" and "TI

XDS110v3"

• Flasher software according to the used ﬂasher adapter

• /RESET, GND and VCC are needed for the JTAG connection

• JTAG connection is supported through the module’s pads i1 to i4

Our binary ﬁrmware ﬁles are not publicly available and require a NDA and licensing proce-

dure for qualiﬁed customers. Additional information is available upon request from

wireless-sales@we-online.com.

Using this method may require a full chip-erase to be able to write a new ﬁmr-

ware into the module.

Never erase the entire chip. Some memory segments (such as CCFG and

FactorySettings) must be retained if original ﬁrmware shall be ﬂashed onto the

µC again. Missing, illegal or erased parameters/ﬂash segments may lead to

module malfunctions when original ﬁrmware is used.
