Hi!

I am works in a project with USB and store values in the EEPROM.
The USB works fine, but when a try to write in the EEPROM the IAP error is 0x0e.

FLASH_EEPROM_WRITE = 61,/*!< EEPROM Write */

wCommand.cmd = FLASH_EEPROM_WRITE;
wCommand.eepromAddr = EEPROM_ADDR + Address_EEPROM;
wCommand.ramAddr = (uint32_t) ptr;
wCommand.byteNum = 1;
wCommand.cclk = Chip_Clock_GetSystemClockRate() / 1000;
Chip_EEPROM_Write(&wCommand, &wOutput);

Any comments or suggestions are welcome

Best regards

wCommand.eepromAddr = EEPROM_ADDR + Address_EEPROM;

Doesn't look right and 0x0e is an 'address not mapped' error. The destination address is a simple zero-based value.

Try

wCommand.eepromAddr = 0;

Thank you for your answer, But the problem persist. Error code 0x0E appear...
Any tips?

Thank you!

Jorge

If you are certain that eepromAddr is now being set OK but you are still getting the 'address not mapped' error that would lead me to believe that ramAddr has an invalid value.

What is the actual value of (uint32_t) ptr?

Dear Chris,

How are you?

Finished!

//Return Code CMD_SUCCESS | SRC_ADDR_NOT_MAPPED | DST_ADDR_NOT_MAPPED
void WriteEEPROM( uint8_t* eeAddress, uint8_t* buffAddress, uint32_t byteCount )
{
unsigned int command[5], result[4];

command[0] = 61;
command[1] = (uint32_t) eeAddress;
command[2] = (uint32_t) buffAddress;
command[3] = byteCount;
command[4] = SystemCoreClock/1000;

/* Invoke IAP call...*/
iap_entry(command, result);
if (0 != result[0])
{
//Trap error
while(1);
}
return;
}

//Return Code CMD_SUCCESS | SRC_ADDR_NOT_MAPPED | DST_ADDR_NOT_MAPPED
void ReadEEPROM( uint8_t* eeAddress, uint8_t* buffAddress, uint32_t byteCount )
{
unsigned int command[5], result[4];

command[0] = 62;
command[1] = (uint32_t) eeAddress;
command[2] = (uint32_t) buffAddress;

Thanks for your help
