HI

I was using the KE15 development board, and then when I looked at the KE15 SDK driver example, I realized that flexnvm eeprom example could only be configured with 32 byte eeprom, but I wanted to configure 2k eeprom, so I read the reference manual to modify:

1. Modified #define EEPROM_DATA_SET_SIZE_CODE (0x39U) to (0x33U) and redefined #define FLEXNVM_PARTITION_CODE (0x3U).

2. Change the length of the write array and redefine it as #define BUFFER_LEN 16

3. Before: result = FLEXNVM_SetFlexramFunction (& s_flashDriver, kFTFx_FlexramFuncOptAvailableForEeprom);To assign a value s_flashDriver. FtfxConfig. EepromTotalSize = 0 x800;

Finally, compile and debug, but HardFault_Handler appears

Thank you very much.

At that time the download program just overwrite, did not forget to erase all, so if you change the parameters of the partition function, to erase all before downloading
