CCS/AM5728: Unexpected program termination

Hello,

Regarding the original issue,

Hi,

I was not able to reproduce your issue.Here is what I did on the latest Processor SDK 5.1 release:

1. I used the UART_BasicExample_idkAM572x_DMA_armTestproject as the baseline (this one enables UART DMA)

2. I added some GPIO library (via .cfg) and header files and GPIO_idkAM572x_board.c into the project to make sure there is

GPIO_v1_config passing into GPIO library.

My code like this:

static bool UART_test_read_write(bool dmaMode)
{
UART_Handle uart = NULL;
UART_Params uartParams;
int length = 0;
uint32_t addrDataPrint, addrScanPrompt, addrEchoPrompt;
UART_Transaction transaction;
bool ret = false;

/* UART SoC init configuration */
UART_initConfig(dmaMode);

GPIO_init();

/* Initialize the default configuration params. */
UART_Params_init(&uartParams);

....

Inside UART_initConfig(dmaMode), I have below:

static void UART_initConfig(bool dmaMode)
{
UART_HwAttrs uart_cfg;

/* Get the default UART init configurations */
UART_socGetInitCfg(uartTestInstance, &uart_cfg);

#ifdef UART_DMA_ENABLE
if (dmaMode == true)
{
#if defined (SOC_AM65XX) || defined(SOC_J7)
uart_cfg.edmaHandle = UartApp_udmaInit(&uart_cfg);
#else
uart_cfg.edmaHandle = UartApp_edmaInit();
#endif
uart_cfg.dmaMode = TRUE;
}
else
#endif
{
uart_cfg.edmaHandle = NULL;
uart_cfg.dmaMode = FALSE;
}
uart_cfg.loopback = FALSE;

if(verifyLoopback)
uart_cfg.loopback = TRUE;
/* Set the DMA enabled UART init configurations */
UART_socSetInitCfg(uartTestInstance, &uart_cfg);
}

I knew that dmaMode is true. By stepping through the code, I also confirmed that UartApp_edmaInit() is called,  GPIO_init() is also called later. I didn't have any issue to run it. My code sequence is:

UART_socGetInitCfg()

UartApp_edmaInit()

UART_socSetInitCfg()

GPIO_init()

In your code sequence:

    GPIO_init();

Are you able to isolate any of below can change the behavior:

1) uart_hw_attrs.enableInterrupt = FALSE 

2) remove two OSAL calls

3) remove board_initGPIO() and AppGPIOinit() 

4) calling UartApp_edmaInit() in between UART_socGetInitCfg() and UART_socSetInitCfg()

For item 3), in your application .cfg file, if you use:

var Gpio = xdc.loadPackage('ti.drv.gpio');
Gpio.Settings.socType = socType;

This will linking with library ti.drv.gpio:./lib/am572x/a15/release/ti.drv.gpio.aa15fg. This library use the default GPIO configuration, you don't need to have add GPIO_soc.c in your application and you should be able to remove the board_initGPIO() and AppGPIOinit() to blink the LED.

If you use: var Gpio = xdc.loadPackage('ti.drv.gpio');

This will linking with library ti.drv.gpio:./lib/a15/release/ti.drv.gpio.aa15fg. This you need add GPIO_SOC.c in your application. See the explanation in:
