- # Introduction
- Basic code to Blink the LED on the MSP430 F5529 Launchpad Evaluation Kit MSP-EXP430F5529LP from Texas Instruments, using the GCC tool-chain from terminal.
-
- # The repository
- This repository includes the `main.c` and `msp430.dat` files required to accomplish the compilation and debuging process.
-
- ## The Code `main.c`
-
- The example code blinks the on board LED attached to **P1.0**, you can copy the contents from here or clone use the file included in the repository:
-
- ```
- #include <msp430f5529.h>
- void main(void)
- {
- WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer
- // PM5CTL0 = 0x0000; // disable high impedance mode
- P1DIR = 0x01; //set up bit 0 of P1 as output
- P1OUT = 0x00; //initialize bit 0 of P1 to 0
-
- for(;;){ //loop
- volatile unsigned int i;
- P1OUT ^= 0x01; //toggle bit 0 of P1
- //Delay
- for(i=40000; i>0;){
- i--;
- __no_operation();
- }
- }
- }
- ```
-
- ## The `msp430.dat`
- The content of `msp430.dat` configures the communication between computer and the launchpad.
-
- Add more description later
-
- # Compiling
-
- ```
- export PATH="/home/gmarx/msp430-gcc/bin:$PATH"
- msp430-elf-gcc -I /home/gmarx/msp430-gcc/include -L /home/gmarx/msp430-gcc/include -mmcu=msp430f5529 -O2 -g main.c -o main.o
- ```
-
- # Debuging
-
- ```
- gdb_agent_console msp430.dat
- CPU Name Port
- -------- ----
- msp430 :55000
-
- Starting all cores
- CPU Name Status
- -------- ------
- msp430 Waiting for client
- ```
-
- In a new terminal tab or window:
- ```
- msp430-elf-gdb --tui main.o
- (gdb) target remote :55000
- Remote debugging using :55000
- 0x00004400 in __crt0_start ()
-
- ```
-
- The agent will response in the other terminal:
- ```
- msp430 Client connected...Connecting to Target
- Found USB FET at ttyACM0
- Target connected...Starting server
- ```
-
- Then, continue in the gdb terminal prompt:
-
- ```
- (gdb) load
- Loading section .lowtext, size 0xa lma 0x4400
- Loading section .text, size 0x2e lma 0x440a
- Loading section __reset_vector, size 0x2 lma 0xfffe
- Start address 0x00004400, load size 58
- Transfer rate: 38 bytes/sec, 19 bytes/write.
- (gdb) b 1
- Breakpoint 1 at 0x440c: file main.c, line 4.
- (gdb) continue
- Continuing.
-
- Breakpoint 1, main () at main.c:4
- (gdb) s 1
- ```
-
- and you will see the code in the terminal running step by step, or write `continue` to observe the LED blinking on the Launch pad board.

- # Problems:
-
- ```
- msp430-elf-gdb main.o
- msp430-elf-gdb: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory
