I'm using the EX-TMC1294XL Launch Pad and was investigating the APIs for EEPROM. I initially created a simple, init, MassErase, Read/Program/Write sequence using the MAP_ API derivatives. All worked well and I removed the MassErase and the Program/Read to simply read what I stored back. All well and good.
Thought I'd change it around and use the ROM_, no other code changes. The Predefines have the proper TARGET_IS_TM4C129_RA1 and PART_TM4C1294NCPDT.
The program crashed in attempting the ROM_EEPROMRead. Funny thing is, if I assembly step through the function, it all works 100%. Just not managing the full speed. I checked ROM_EEPROMStatusGet prior to calling the Read, but still no joy.
Here's the pertinent code lines:
g_ui32SysClock = ROM_SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |
SYSCTL_OSC_MAIN | SYSCTL_USE_PLL |
SYSCTL_CFG_VCO_480),
120000000);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_EEPROM0);
eeStat = ROM_EEPROMInit();
eeStat = ROM_EEPROMSizeGet();
System_printf("SIze of EEPROM %d\n",eeStat); <--------- This reports just fine
System_flush();
while(ROM_EEPROMStatusGet());
ROM_EEPROMRead(eeRead,0,sizeof(eeRead)); <---------- full speed crashes; walking steps works
Thanks
