AM2634: qspi flash erase and write

Tool/software:

I'm having issues getting basic erase and write to work with the NOR flash on the AM2634-C launchpad.  Could someone please let me know an easy way to implement erase, write, and read.

I've tried the below example code from MCU plus.  The RxBuf is always 0.

QSPI_init();
QSPI_Handle qspiHandle = QSPI_getHandle(CONFIG_QSPI0);
err = QSPI_norFlashInit(qspiHandle);
err = QSPI_norFlashRead(qspiHandle, FLASH_OFFSET, gQspiRxBuf, 256);
err = QSPI_norFlashErase(qspiHandle, FLASH_OFFSET);
err = QSPI_norFlashRead(qspiHandle, FLASH_OFFSET, gQspiRxBuf, 256);

I've also tried the below code (by copying in an example.syscfg file).  but my project doesn't start.  I set a breakpoint at the beginning of main() but it doesn't get there.  If I use my own example.syscfg in CCS, the SYSCFG tool crashes when I add in the "flash" module.

Flash_getAttrs(CONFIG_FLASH0);
(void) Flash_offsetToBlkPage(gFlashHandle[CONFIG_FLASH0],offset,&blk,&page);
(void) Flash_eraseBlk(gFlashHandle[CONFIG_FLASH0], blk);
Flash_read(gFlashHandle[CONFIG_FLASH0], offset, gQspiRxBuf, APP_QSPI_DATA_SIZE);

Here are the details:
