FlashMagci couldn't read EEPROM of LPC546xx

[lihao_boy_123]

Hi,I'm a LPC546xx MCU developer. I have some problem and need to check EEPROM data of LPC546xx by UART ISP.

But Flash magic (Version:11.20) don't support  reading EEPROM yet. While LPC546xx User manual says read EEPROM by UART ISP is valid.

Could anyone share some tools or experience? or terminal tools of Flash magic would do some help?

Thanks!

The Addr is 0x40108A00~0x40108C00, 512 Byte in totall.. I could read it by download a new program without erasing the past EEPROM and then the program printf the data.

  But it is a better choice for debuging if I could read it without reprogramming.  Thanks~

It's a dead posting but I had a similar problem, and find a convenient solution. So I will leave it here, maybe it will become in handy for somebody.

If the firmware is already present on the chip and EEPROM is inited then Jlink can read EEPROM data with the mem32 command.

Launch Jlink commander software

Connect to the chip.

For LPC546xx

Execute mem32 40108000 1000

Where 40108000 is an EEPROM start address, 1000 EEPROM size / 4.

This should print all EEPROM content to the Jlink commander.

Hi lihao.boy.123@163.com,

I tested LPC54608 EEPROM reading with Flashmagic without success.

I wonder this is a problem of Flashmagic.

Flashmagic is not NXP SW, it is produced by Welcome - EmSA .

I suggest you contact esacademy support or support@esacademy.com

Have a great day,
