CC2530: Unable to get ZNP UART transport mode working

Mark Munsters

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK, CC-DEBUGGER

Hi,

I'm trying to get the Z-Stack 3.0.2 ZNP image for a CC2530 target to work.

I successfully build in IAR the Z-Stack 3.0.2 ZNP CC2530 image and downloaded it on the target using a CC-DEBUGGER.

The CFG1 pin is set to low to select the UART transport mode. The CFG0 pin is set to low, no 32kHz crystal is connected. The RESET_N pin to high.
I expect the SYS_RESET_IND command to be sent after powering up. Instead, using a logic analyzer, I see some garbage, framing errors.

Any help would be appreciated, I'm running out of ideas.

Try to hard code "znpCfg1 = ZNP_CFG1_UART" and "znpCfg0 = ZNP_CFG0_32K_OSC;" in InitBoard of your ZNP code to test again.

Hi Mark,

Please check the Defined symbols from Project Options -> C/C++ Compiler -> Preprocessor to confirm that the correct definitions are set as expected. Have you tried connecting Z-Tool with the default 38400 baud rate and flow control (RTS/CTS) enabled? These can be modified from MT_UART.h to fit your project requirements. I also recommend reading the Z-Stack ZNP Interface Specification located from the Z-Stack 3.0.2\Documents\API folder, as well as reviewing Similar E2E topics. Are you able to further debug the board to understand what is being sent/received?

Regards,
Ryan

Hi Ryan,

Thx for responding (YiKai also)!

I hoped I didn't had to get familiar with this codebase/environment and just use it.

Are there no precompiled images available?
