Hi, I've purchased a Ti's evaluation board for the AD converter ADS1232 REF and i've been having some problems.
1) When I build the original firmware of ADS1232(version 1.1.0) the compiler displays the following error,
uart.c: In function 'uart_init':uart.c:27:2: error: 'port4' undeclared (first use in this function)
I'm using the shell cygwin and the last version of mspgcc in Windows XP.
2) When I try download the firmware to ADS1232REF via BSL, the makefile no found the programmer msp430-bsl. I look everywhere and can't find
Is there any ideas of what's going on? Any way of solve this problem?
Thank you

Welcome to the forum! You are embarking on a very complicated process. Basically the compiler cannot find the definition for the MSP430 ports used for the MSP430F449. There may be something missing in the default path assignments regarding MSPGCC.
Regarding the downloading of the firmware, there are two methods possible. The make file uses JTAG, and that requires a JTAG programmer for the MSP430. The actual call is for a parallel port programmer MSP-FETP430IF. So unless you have that particular device, you should comment out the line in the make file.
The actual BSL can be done through the USB connection, but requires a downloader program. One that can be used requires that the TUSB3410 drivers have been installed. This was done if you have installed the Labview code that controls the ADS1232REF. The download program is called Simpleflash and can be downloaded from the ftp site at this location:
ftp://ftp.ti.com/pub/data_acquisition/ADS1256_on_HPA449/
Changing the firmware is a very ambitious process, and altering the program should require knowledge and proficiency in the use of freeRTOS. The ADS1232REF was designed as a reference design for weigh scale applications. Firmware support of altered code will be minimal, as this system was not designed as a development system.

Bob,
That worked perfectly! Thank you very much.
