prix 0 Posted February 11, 2011 Share Posted February 11, 2011 Hello! Has anyone set up a working UART with MSP430 FET (launchpad or ez430) on Windows 7 64-bit. I have installed latest CSS and drivers for MSP430 FET installed correctly. I can program chips, do debugging and so one.. But when I try to observe UART activity on COM port, there's nothing. I attached RF2500 daughterboard to ez430 and launchpad, but there is nothing to see when looking at COM port with serial monitor... I'm pretty shure I configure it correctly, 9600 bauds, 8bits, 1stop bit, no parity... Then I attached hardware UART analyzer, the famous Piratebus and configure it to observe UART. BINGO... I get what I should and RF2500 reports voltage and temperature over UART... Has anyone got similar problems??? Thanks Quote Link to post Share on other sites

You mean you configured it so as to simulate the RF2500? Looks like a hardware problem on the RF2500 side. Quote Link to post Share on other sites
prix 0 Posted February 11, 2011 Author Share Posted February 11, 2011 No I did not configure it to simulate RF2500... I just sniffed UART's TX and RX lines with PirateBus configured as UART monitor... Scheme: win7x64<====>FET <====> RF2500 ...........................| ...........................| .......................piratebus What I saw, is that there is UART activity but none is displayed on computer's serial monitor. Seems like software issue to me and definately not hardware issue. Probably buggy x64 drivers for TI Flash Emulation Tool and USB chip. I even tried UART echo example in the same way, same results...

bluehash 1,581 Posted February 11, 2011 Share Posted February 11, 2011 According to this, it seems to work on 64bit Win 7. There's something going on in the FET. Quote Link to post Share on other sites
bluehash 1,581 Posted February 11, 2011 Share Posted February 11, 2011 Also: For those wondering I have found the explanation. Basically, the windows driver used by the MP430 Application UART, seems to have extreme problem with usb hubs. After quite a lot of hair pulling, multiple odd drivers, and disabling a lot of windows components, it appears that just plugging the device into a direct port(not a hub port) works perfectly.

prix 0 Posted February 11, 2011 Author Share Posted February 11, 2011 Nah... changing usb port from hub directly to motherboard USB port doesn't work eighter... My launchpad is using generic windows usb device driver? Same with yours? Anyone actually got working example with win7-64? Quote Link to post Share on other sites
bluehash 1,581 Posted February 11, 2011 Share Posted February 11, 2011 Any other USB devices plugged in, other than your keyboard /mouse. Quote Link to post Share on other sites
prix 0 Posted February 11, 2011 Author Share Posted February 11, 2011 Ok, I have been testing things out and this is what I found out: I tired NJC's UART example with Launchpad and MSP430G2231 chip. I looked at serial port activity with RealTerm and BINGO. It is working as it should. So drivers are ok and hardware also... Then I tried connecting RF2500 daughterboard to 6-pin J4 ez430 connector on Launchpad. RF2500 starts the RF communication, LEDs start blinking, but fails to transmit anything over UART. No serial port activity on computer, though if I attach hardware analyzer I can see that RF2500 is transmiting... Possible drivers or FET firmware failure... Then I even tried EZ430U FET which came with EZ430-F2013 bundle. I connected RF2500 to it and observed if anything would happen on computer's serial port... but there's noting... So again possible drivers or FET firmware failure... Then I went on googlin'... found this: http://processors.wiki.ti.com/index.php/EZ430-RF2500 <- Part which says: "Are you using a valid OS? (The EZ430 only works with 32-bit Windows Vista and XP)" http://processors.wiki.ti.com/index.php/EZ430_Emulator_Upgrade <- Part which says: "he firmware on the eZ430 emulator can be manually upgraded in order to add new functionality such as the Application UART and to support additional MSP430 devices." Things that bother me... I am using 64-bits OS which is not supported by RF2500 demo app, but I think this should not be problem... And that I should upgrade firmware on ez430 to gain Application UART functionality... Any other thoughts and solutions? Quote Link to post Share on other sites
bluehash 1,581 Posted February 11, 2011 Share Posted February 11, 2011 the link to the TI groups I sent earlier had someone who said it was successful for him, so it should work on yours. - Try reinstalling the driver. - Plugin your USB ports at the back of the PC, rather than the front. The front ports are sometimes a hub extension. Quote Link to post Share on other sites
TheDirty 33 Posted February 12, 2011 Share Posted February 12, 2011 Look at the device manager. You should have a port entry like this. Never used the EZ430-RF2500 UART, though so I can't confirm that it works for me. I have a lot of other serial->USB converters to use. Quote Link to post Share on other sites
lotus77 1 Posted January 2, 2014 Share Posted January 2, 2014 Was there ever a solution to this problem? I see the same thing on my system and I can't get very far apart from it working 1/100 times I connect the USB port. Quote Link to post Share on other sites
