It is not entirely clear from the datasheet, but it appears that the LPC2458 external memory controller (EMC) is limited to addressing two 1MB blocks of external asynchronous stati...

Dear All,
I want to save some working critical data to flash in my project.
I need to save the same before the unit is powered down.
I am using EINT2 to trigger flash writin...

As mike says... you should switch off interrupts. Because during IAP flash
writesthe flash (ALL of it, not where you're writting) becomes unavailable
to the processor,
so... if...

NXP user manual for 2106 says the IAP copy RAM to Flash command accepts a count of 256 to 4096 bytes. My code works properly for 512 bytes but a count of 256 yields an invalid co...

Please check whether LCP2478 has IAP functionality. If yes then you can mak=

Here is solved the question I proposed last week.
It was necessary to map interruption vectors of the Application program (which is at 0x80010000) to RAM memory.
The solution t...

not. I use an intermediate serial flash to hold the file from the SD
card. I compare byte for byte the co...

I looked at J.Cs code, but he uses assembly language, which is not the
way I am doing IAP. I am using the way the user's manual describes on
pages 309-310 under IAP commands.

I'm assuming the LPC2148 bios doesn't allow recursive calls to

my 'erase sectors' routine. It locks up....

Sutton Mehaffey - Jul 15 2009
In programming a LPC2148 with IAP, if I erase all sectors, what causes
the JTAG not to work until I reload serially? Trying to understand it.

Girish Pundlik - Jun 29 2009
Addendum:
I have considered using external serial EEPROM that will give 1M write cycles, but is too slow for the purpose, while a battery backed nvRAM would be too expensive.

Hi Sutton,
the other way would be to have very primitive "bootloader" (which would fit
in 4kB, because no SD/FAT code), after that the main app and after that the
place for ...

writes. The on-chip...
