Hi,
I'm new member and newbie. I' ve a question regarding receiving a software from a friend using Red Suite. He told me to change Project Proprieties --> MCU Settings --> Flash location from 0x000000 to 0x30000and size from 0x80000 to 0x50000
But I think is impossible in my environment LPCXpresso 3.6.2, is it correct?
Many thanks
zerep

Just change your MCU settings:

Project -> properties -> C/C++ Build -> MCU settings -> Memory details

Note: Don't know why you are using an antique version, the actual is 4.2.3 :D

Yes, LPCXpresso version 3.6.2 does not have this config interface. Upgrade your IDE to the latest version and you will be able to do that.

Hello Zero:

I am a newbie too. I would like to use a sector or a block of the 128K of LPC1227's flash to store some configuration data (non-volatile). Can I program a particular sector only while reading/executing code from flash?

Thanks,

agatsu

That's described in your UM: 20.5.2.1 Information block

Of course IAP is possible while your MCU is running from Flash.

But don't forget your interrupts:

Quote:

20.5.5.7 Interrupts during IAP
The on-chip flash memory is not accessible during erase/write operations. When the user application code starts executing the interrupt vectors from the user flash area are active. The user should either disable interrupts, or ensure that user interrupt vectors are active in RAM and that the interrupt handlers reside in RAM, before making a flash erase/write IAP call. The IAP code does not use or disable interrupts.
