LPC4370 firm

[takuyahasegawa]

We use LPC4370 for senssor signal processing.
We have trouble that firm data inside LPC4370 is initialized during power off for 3days.
And then we have rewrote data to LPC4370, that oparate nomally.
So, we guess that that is CPU trouble.
If you have any coping method, please let me us.

Thank you

Now I use senssor signal proessing board that consists LPC4370, and I write firmware

into the board.  

 "LPC4370 Block diagram"  descrives that LPC4370 has 64kB ROM.

So I think that firmware is written into that 64kB ROM.

Is this 64kB ROM just read only?

Hi,
The ROM 64 KB section is used to store the bootloader, it's forbidden to program or write data this section.
Hope this is clear.

Have a great day,

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
The LPC43x0 series doesn't contain internal flash, only SRAM, so these chips would lose data after power-off.
Hope this is clear.

Have a great day,
