Other Parts Discussed in Thread: SYSBIOS, CC2650, CC1350
Hi,
I loaded two applications in the CC1310 flash.
The first one is located at address 0x0000 and the second at address 0xA000.
In the first application, I want to jump to the second application if the button is pressed.
I made the following program and it is working! I am able to jump to the second application when using that program:

void echoFxn(UArg arg0, UArg arg1) { uint8_t ch; while (1) { Task_sleep(1000); // THE JUMP STOP WORKING WHEN THIS PART IS UNCOMMENTED // if(!UART_read(uart, &ch, 1)) // { // // Do something // } // else // { // // Do something // } } } |
That is the only change from the working program to the one that doesn't work.
I don't know if it is relevant, but in both applications I commented:

/* ================ ROM configuration ================ */ /* * To use BIOS in flash, comment out the code block below. */ /* var ROM = xdc.useModule('ti.sysbios.rom.ROM'); if (Program.cpu.deviceName.match(/CC26/)) { ROM.romName = ROM.CC2650; } else if (Program.cpu.deviceName.match(/CC13/)) { ROM.romName = ROM.CC1350; } */ |
Can someone help me to understand why the jump stop working when I used the uart driver?
