CC2530 SYS_RESET_IND

Other Parts Discussed in Thread: Z-STACK, CC2530, CC2530EM

Hi,

I am using a CC2530EM with firmware CC2530ZNP-Pro.hexfrom C:\Texas Instruments\Z-Stack Home 1.2.0\Projects\zstack\ZAP\ZNP-HexFiles. I'm programming it per SPI. After reset I'm reseiving data from SYS_RESET_IND: 0x19, 0xBF, 0xFE, 0x3E, 0xE9, 0xE0. After changing delay time after sending poll command or SRDY go high, data changed, but still stay wrong. Where could be an error? Thanks.

What do you mean "still stay wrong"? You can refer to the ZNP wiki at http://processors.wiki.ti.com/index.php/Simple_Applications_Examples

Thank you for helping. The application processor sets CC2530 RESET_N pin high and CC2530 starts operation. Application processor receives the SYS_RESET_IND message. I should receive 6, 41, 80, 0, 2, 1, Major release number, MinorRel, Hardware revision number. Instead I'm receiving another sequences. I was changing the clock speed of SPI, delay time between poll commands, but it didnt help.

If it is possible, I would suggest you using Z-tool to make it work first.

Did you try changing the clock polarity and phase?

No, I didn't. I'll try. Thank you

I've watched signals on oscilloscope from stm32f401c-disco and from smartrf05 board, phase and clock polarity are the same, on every request (poll or SPSP) CC2530EM responses with 0x73. What else could I try? Thank you.

I've noticed, that no matter what data I'm sending to CC2530EM during SPSP: zeros, nothing or another sequences, it responces with random numbers. Could be there hardware problems with CC2530EM? Thank you

Can you send an Oscilloscope trace of SPI CS, Clock, MRDY and SRDY?
