Hi everyone, I'm using Gcc compiler 4.1.2 found inside WinARM. I have 64 MB SDRAM and 500k FLASH on my board. I'm using Flash Magic for programming. I'm looking for a way to store very large constant array directly to FLASH. This array should be preloaded to FLASH, before I start my program. The size of array will be about 200-250k. Unfortunately, FLASH Magic doesn't have Send File comman...

Hi - We use LPC2148 in our product. We are using flash to store image data to be shown on the screen. In some of the boards (around 5% of boards), we are facing issue while reading the flash data.

Hi, ? I am working on the setting up the external flash for LPC2478. Currently I am facing the issue with executing the code from External NOR flash. ? The size of the internal flash in LPC2478 is 512K. Since the application requires more memory than 512K, it has been decided to use the external NOR flash. I have set the MEMMAP to 3 in the cstartup.s file so that the bootloader remaps the ve...

Hi All, I am planning to use LH79520 in a project. I have a basic Q. LH79520 is a ROMless device (at least the one from NXP does not have in-built flash, the sharp device has some in-built flash). How do I write the program in the flash? One way of doing this is executing the code from SRAM and writing in the flash from there. Is there any tool available that supports different t...

He is using the IAP function to start the bootloader. This seems to work so far. He can delete sectors BUT as soon as he wants to write to the Flash the Flash is unlocked and he can't write to it.

I recently switched development boards from the Olimex LPC2138 to the LPC2148. Now it seems that the standard Philips Flash Utility (ver. 2.2.0) that I was using for the LPC2138 does not include the LPC2148 in its supported devices list. What are you using to program the flash on the LPC2148? Is Lpc21isp the only free Win tool for flash programming on the LPC2148? Thanks, Paul

Hello, I am using an LPC2210 on Phytec Board, and (I assume) you all know that the LPC2210 does not have an internal flash, nor does it have IAP.

My question is, is it possible to use some memory locations or sectors of external flash as eeprom, or a place to stor...
