nickn 5 Posted September 20, 2014 Share Posted September 20, 2014 I've been thinking about using the f5529 launchpad board to program my g2553 chips. From what I understand, all I have to do is simply connect: programmer side of board | g2553 3.3v == vcc pin gnd==gnd RST == RST TEST==TEST optional for UART: RXD == RXD TXD == TXD And of course a 47K pull-up for RST and a 1 nF cap between RST and ground. Is it that easy? The reason I wanted to use the f5529 board was to get around things such as the 9600 baud serial limitation and such. Quote Link to post Share on other sites
Fred 453 Posted September 20, 2014 Share Posted September 20, 2014 That sounds right. Quote Link to post Share on other sites
nickn 5 Posted September 20, 2014 Author Share Posted September 20, 2014 I had a spare g2231 chip lying around and tried it in Energia and got: tilib: MSP430_OpenDevice: Unknown device (error = 5) tilib: device initialization failed Perhaps the issue is that Energia ties certain programmers with certain chips?

Rickta59 589 Posted September 20, 2014 Share Posted September 20, 2014 For testing try this .. Remove everything except the 3.3+, gnd, test, reset. Get rid of the cap, led, led resistor .. resistors to power and gnd run a wire from power rail gnd to gnd run a wire from power rail 3.3v to vcc See if you can program it. If so, add back in the led and resistor led. nickn 1 Quote Link to post Share on other sites
Rickta59 589 Posted September 20, 2014 Share Posted September 20, 2014 BTW: You do have the msp430g2231 selected in Energia yes? Quote Link to post Share on other sites
nickn 5 Posted September 20, 2014 Author Share Posted September 20, 2014 I do. I did what you said (those resistors connected to vcc and ground pins are simply 0 ohm jumpers) and it worked, apparently it was the capacitor connection that it didn't like. Thanks!

Rickta59 589 Posted September 21, 2014 Share Posted September 21, 2014 I've mostly been using the latest FRAM Launchpad as of late. Today, I spent some time trying to debug and load code using the latest MSP Debug Stack with these G series chips with the FET on an MSP430F5529-LP. I did experience some serious flakiness. There does seem to be issues using the latest firmware. Aside from random errors while trying to debug I've also noticed that the UART is much slower. (I'm using 32 Bit Ubuntu 14.04 ) I rolled back and loaded older firmware multiple times until I found one that worked well with these G series chips. I ended up with the libmsp430.so from CCS 6.0.0.00190. That seems to be the newest one that works reliably. -rick Quote Link to post Share on other sites
