CC2630 ROM bootloader by default

Michael Eicher65

Other Parts Discussed in Thread: CC2630, CC2650

I want to program the CC2630 the first time (shipped on a reel) with the serial ROM bootloader.

How does the CC2630 ROM bootloader work by default?

Table 8-2 CC26XX technical reference manual:
There are described the given pins for UART and SPI.
Which is the default backdoor pin? Do I need a default backdoor pin for the first time programming?

Regards

Hi

I've got an additional Problem.
There is a discrepance between "technical reference Manual swcu117g" and "serial bootloader interface swra466a":

swcu117g (page 697) :
SSI0 RX DIO_11 (5x5)
SSI0 TX DIO_12 (5x5)

swra466a (page 6):
SPI MOSI DIO_11 (5x5)
SPI MISO DIO_12 (5x5)

I'm a little confused. But at a CC2650 master output (MOSI) should be a TX and a master input (MISO) should be RX.

What is right? Is the CC2650 a SPI slave in swra466a?

Regards
Michael

If you use SPI for CC2650 backdoor boot loader, it acts as SPI slave. MOSI on CC2650 means the same as SSI RX.
