I hope you can help me..
I'd like to start programming my ARM Cortex M3 and I've bought a JTAG adapter.
I'm not able to understand how to connect the ARM to the JTAG adapter.
ARM datasheet: http://docs-europe.origin.electrocompon ... db0f69.pdf
JTAG datasheet: http://docs-europe.origin.electrocompon ... e24b5a.pdf
In the ARM datasheet there is written:
The ARM SWJ-DP Interface is embedded, and is a combined JTAG and serial wire debugI just have to connect TDI, TDO, TMS and TCK which are present on the JTAG adaptor to the equivalent ARM pins or I have to do some other connections?
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a
specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.
Should I have to connect Vcc to my ARM or not?
I've tryed to search on google but I wasn't able to find any document or schematics which can help me with the connections.
Can you help me, please?
I'd like to know the correct procedure which can let me to connect my ARM with the JTAG adapter which I have.
Thanks to all.
