How to read EEPROM data from LPC4357?

[ayemin]

Dear All,

I am repair technica.I got one device (DSE7320MKV7.2)which is use NXP LPC4357.This device has pin lock.I think pin lock code store in EEPROM.So, I wana read and write EEPROM data only. Please guide me how i can do it?

Thanks All

Hi,

Can you tell us the interface of external EEPROM?  it can be spi, I2C or EMI. If you connect the EEPROM with the  EMC(External Memory Controller), the LPCOpen provides the EMC driver for static SRAM.

after you run the example, I suppose that you can read the EEPROM with a specific SRAM address with the debugger of MCUXPresso.

You'd better provide the schematics so that we can get the EEPROM address and the application code.

If you can not provide the schematics and application code, it is a bit difficult to support.

After you install MCUXPresso tools, you can access the LPCopen package from the directory.

Hope it can help you
