CC3200: choose between CC3200 SRAM and CC3200 Flash

[rei-vilo]

Add another board at the menu Tools > Board > LaunchPad w/ CC3200 SRAM (80 MHz) to the existing LaunchPad w/ CC3200 Flash (80 MHz).

This would allow avoiding the J8-SOP2 strap as well as debugging #417.

I did think about doing this but it's a bit tricky to do from the Energia IDE. I have not found a way to upload to RAM and then detach the debugger. As soon as I detach with OpenOCD the code stops running. Ideally I would call OpenOCD directly without GDB -> upload to RAM -> terminate OpenOCD. If anybody knows how to achieve this then I would love to hear about it.

[rei-vilo]

I've found a solution using the debugger solely.

Launch openocd in a first terminal window and then arm-none-eabi-gdb in a second terminal window.

When the gdb prompt appears on the second terminal window, enter the following commands:

file '/Users/ReiVilo/Documents/Projets/eX/eX-CC3200/eX-CC3200/Builds/embeddedcomputing.elf'

set remotetimeout 2000
target extended :3333
monitor reset halt
load
monitor reset init 

continue

Works fine for me, so I'm closing this ticket.

Notes

• Remove the strap J8-SOP2 and place the jumper J8.
• Sketch goes to RAM and is lost if the LaunchPad is powered down.
