How can I completely erase LPC11E67 memory and set it to new controller condition

[karthikhosavara]

I am using an LPC11E67 microcontroller. I am using Program flash to erase microcontroller memory but I don't think it is been set to default condition as new. How can I do it? 

[lpcxpresso_supp]

LPCXpresso IDE (or the newer MCUXpresso IDE) can be used to erase flash using the "GUI Flash Programmer" via a debug probe such as LPC-Link2.

See https://community.nxp.com/message/630784 for LPCXpresso IDE, or else chapter 10, "LinkServer Flash Support" of the MCUXpresso IDE v10.0.2 User Guide.

Regards,

Hi,

Thanks for the reference. But I am using LPCxpresso v8.2.0 for software development and OM13058 board for debugging.  

How can I use the LPC xpresso to erase the LPC11E67/8. If you prefer using flash magic. Do I need an additional setup of debugger to do that? If yes what is the part number and where can I buy that.  

Thanks for your support.

Hi Karthik Hosavaranchi,

You need to install the Flash Magic too and buy a UART to USB adapter, you can learn how to use the Flash Magic via the thread: https://learn.adafruit.com/getting-started-with-the-lpc810/programming-the-lpc810-with-flash-magic

Hi Karthik Hosavaranchi,

Thank you for your interest in NXP Semiconductor products and 

for the opportunity to serve you.

I'd like to suggest that you can use the Flash Magic to complete erase the MCU.

Could you suggest me the hardware connections between the board and Jtag?

Hi Karthik Hosavaranchi,

Whether you want the referring design of the debug interface, if yes, I'd highly recommend you to referring to the OM13058: LPCXpresso LPC11U68'sch.

Hi jeremyzhou‌,

I have used the evaluation board and LPC Xpresso for my development. now I need a standalone programmer for production. LPC Xpresso software develops .afx file, if I use the command conversion to hex file it's not working it displays error in 4097 line. and moreover, if you could suggest me a way for hardware connection and output file format to load. it would be of a great help. please suggest a standalone loader that will use .afx format so I can eliminate any intermediate errors. 

thanks 

Karthik

Hi Karthik Hosavaranchi

Thanks for your reply.

I don't think create a standalone programmer to load the AXF file is reasonable way, in opinion, I'd highly recommend you to transfer AXF file in other format file such as:

• srec
• binary
• ihex
• tekhex

And you can learn the the transition way by referring to the thread.

Generating srec, binary and ihex files 

Have a great day,

Hi jeremyzhou‌,

i was able to convert it to other formats. but could you share the command to convert it to tekhex format. 

[jeremyzhou]

Hi Karthik Hosavaranchi,

The convert command is below.

arm-none-eabi-objcopy -O tekhex example.axf example.hex

Hi jeremyzhou‌,

I tried it. but it's not working.

[jeremyzhou]

Hi Karthik Hosavaranchi,

Sorry, the correct convert command is indicated below.

arm-none-eabi-objcopy -O tekhex example.tekhex example.tek
