CC2640R2F: Load program on CC2640 Package 32-Pin (5-mm × 5-mm) using LAUNCHXL-CC2640R2 (CCS v9.2)

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640, LAUNCHXL-CC2640R2,

Hi!

I'm trying to program a custom board with CC2640 MCU (package 32-Pin -5-mm × 5-mm) using LAUNCHXL-CC2640R2, but every time I try to do it and I get a message saying that CCS couldn't connect to target:

Error connecting to the target:
(Error -241 @ 0x0)
A router subpath could not be accessed.
A security error has probably occurred.
Make sure your device is unlocked.
(Emulation package 8.3.0.00003)

I've tried to add CC2640R2DK_5XD at the predefined symbols but I got some compilations errors because the cc2640r2em_board.c and cc2640r2em_board.h files related to it were unavailable.

I'm using sdk v1.50.0.58.The files needed seem to only be available at sdk v4.40 at the folder C:\ti\simplelink_cc2640r2_sdk_4_40_00_10\source\ti\blestack\target\cc2640r2em.

I have no idea about CC2640R2DK_5XD correspondence with my issue.

Hi,

Although the device initialization can perhaps prevent the device from properly booting, please check error 241 at the Debugging JTAG page below (search for the error number):

https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html

Hope this helps,

Rafael

Hi Bruno,

You should resolve first your JTAG connection to custom board. The relevant connections are JTAG_TMS, JTAG_TCK, nRESET, and GND. Use SmartRF Flash Programmer 2 to check whether your custom board is being detected.

You can modify the Launchpad board files to work with 5x5 CC2640R2F.

Hi!

I'm using HM 17 module. I tried to use SmartRF Flash Programmer 2 but the MCU is not being detected there.

Regards

Bruno

Hi Bruno,

Seems the HM-17 module has only UART interface for programming. https://tasmota.github.io/docs/HM-17/

Hi!

Thanks! Actually I've found that HM-17 has two more JTAG pins (TDO and TDI). So I used them and could successfully program my module.
