What do you need to program and use Hercules LaunchXL-TMS57004

[jfm92]

Upload and debug:

For this board we have two different way of use:
First using the micro USB connection and the TI Uniflash Tool
The second option is J-Link programmer.
J-Link
You can buy an adapter to 14 pins or do the next wiring:

Jtag-Pin	JTag Signal	J-Link Pin	J-Link Signal
1	TMS	7	TMS
3	TDI	5	TDI
5	PD	1	VTref
7	TDO	13	TDO
9	RTCK	11	RTCK
11	TCK	9	TCK
13	EMU0*	-	N/C
2	TRTSN	3	nTRST
4	GND	2	GND
6	N/C	-	N/C
8	JTAG_SEL	4	GND
10	GND	6	GND
12	GND	8	GND
14	EMU1*	-	N/C

And for the supply of the board, I connect the USB of the board.

To upload the code, follow the next steps:

Execute in the termianl /usr/bin/JLinkExe (It's by default in Ubuntu)
When the program is executing you must type the next commands:

• connect
  (A this moment will ask for some options, you must write the next to have a successful connection)
  -TMS570LS0432
  -J
  -default
  -default

The console will return this:

About the final error, I'm still figuring out what it means. But anyways it connect correctly.

Now type "r" to reset the device.

Then it's necessary to erase the flash, so type "erase" and wait.

Then upload the code to the board.
Type: loadfile nuttx.bin,0x0
(Note you must working in your nuttx folder)
And if everythings goes fine it should return this:

Serial console:

TTL-232R-3V3
But it's still not working.
