Questions about how to program a CC3200 based custom board

Other Parts Discussed in Thread: CC3200MOD, UNIFLASH, CC3200

Hello,

I worked on the LaunchpadXL evaluation board, and now I am making a custom board based on the CC3200MODR1M2AMOB module and I am not completely sure on how to program it.

I have done my schematics based on the docment "CC3200MOD SimpleLink™ Wi-Fi®and Internet-of-Things Module Solution, a Single-Chip Wireless MCU" part 6.1 (page 51).

I have included two headers in the schematic in order to connect JTAG & Flash Programming pins.

I have 3 questions :

1. How to flash the Flash memory?

I am wondering if I must have a specific programer to be connected to the 4 wires Flash Programming header

OR if I can use the pins available on the LaunchpadXL after removing the appropriate jumpers, so I can flash it

through the USB port using Uniflash ?

2. How to Debug my code through the JTAG interface ?

Do I need a specific programer (like Atmel JTAG-ICE) to download the code from the IDE (Code Composer Studio) to the CC3200 module

OR can I use the JTAG pins on the launchpadXL after removing the appropriate jumpers, so I can here again use the USB and the

JTAG emulator on the LaunchpadXL ?

3. How do I need to wire pins 46 & 47 to use UART1 for an external device ?

pins 46 & 47 are directly wired to the Flash Programming header and I am not sure on how to connect a device to use thoose lines

regards,

Yoann

Hi Yoann,

1. How to flash the Flash memory?

You can use the Launchpad & Uniflash Tool to program your target board. In order to do that you just need to connect the following signals to program your target board:

CC3200 Launchpad	CC3200MOD Target Board
J6 (TX of FTDI)	Pin 47 (UART0_RX)
J7 (RX of FTDI)	Pin 46 (UART0_TX)
RST	Pin 35 (nRESET)

Also note that Pin23 (SOP2) should be pulled high when flashing.

You can use the JTAG pins on the Launchpad (TCK, TMS, TDI, TDO) to debug your target board.

Hi Vaibhav ,

Thanks for your answer, this is helping me in doing the rights choices to design my board.

I am still wondering about the third question : How to wire pins 46 & 47 for an external device through UART ?

cheers,

Yoann

HI Lecat,

For those lines, just make sure you don't have 2 TX lines connected to the same node at the same time.

Hi Aaron,

yes I've just put some jumpers like in the photo.

HI Yoann,
That looks fine, are you having an issue with it?

Hi,

no I haven't. At least not yet ! my boards aren't built yet

I just didn't want to had more jumpers on my board but it seems like the only solution

so I just posted this picture to show how I solved my "problem" if a lost fellow see my post.

But thanks for proposing your help

Yoann
