I am using lpc2103.till now I am using IR sensor to send motion then send the message through pc connect via RS-232 to ARM. I want to interface a camera with the board but lpc2103 memory is less. Could somebody please help in how to interface off chip flash memory then load OS kenel into flash.Is this a good idea by the way. Please help me I am just a begineer. Any help would be really a...

I'M RUNNING THE IAPs FROM RAM ITSELF AND REPLACING THE CODE ALREADY PRESENT AT 00 LOCATION IN FLASH BY THE CODE RESIDING IN RAM. PROBLEM IS THAT THE CODE GOT REPLACED BUT NEW CODE IS NOT GETTING ACTIVATE, INFACT AFTER MANUAL RESETING IT IS NOT WORKING. WHAT WOULD BE THE PROBLEM AND SOLUTION....... ------------------------------------

Hi, Today I downloaded flash utility v2.2.3 from philips website for lpc2148. after successful installation when i ran that program i couldn't change device. All other buttons works except the device selection. Another interesting thing is - when I change device from my prior installation (v2.2.0) and then run v2.2.3 again then the chaged device is shown in that. I tried by unins...

I'm creating a data logger using the LPC2129 and need to store configuration data, even when my SD card might become corrupted. I'm trying to use code from AN11008, using FLASH as EEPROM, modified to store a single, short text file. I think my read functions work properly, but writing to EEPROM seems to fail. I'm having trouble wrapping my head around all of this, so I would really appreciate a...

Hello I try to run simple circuit with LPC2138 chip. I plan to use lpc21isp utility to flash it under Linux. Yesterday I installed GCC-4.0.1 from gnuarm.com, BUT I did not find lpc2138.h, startup.S and .ld files to build code for FLASH and RAM of LPC2138 chip. Please, give me some advice where better to download these things? Sample code for LPC21xx wi

Hi All- I'm currently experiencing a very frustrating issue with the LPC2138 bootloader. I can successfully and reliably use the Philips flash utility to download an image to a blank LPC2138 once and only once. After that, the flash utility is never able to communicate with the LPC2138. I have been monitoring the recent bootloader thread that was resolved by manipulating the watchdog

I am debugging some code supporting write of some default data to flash (bank 15 on LPC1752). The problem is that erase and copy ram to flash functions hangs up during debugging. Studying a little I discovered that lPC internal functions need the last higher 32 byte of ram and also that there is a gdb bug that seems to require the last 16 byte of ram. So, is there any other engineer having ...

Greetings: I successfully completed James Lynch's excellent tutorial using an Olimex LPC2148 header board. I was able to flash a LED by executing the gcc compiled examples loaded into either RAM or FLASH memory. However when I try to expand the tutor example by adding calls to library functions I find I get loader errors. It would appear the loader is able to find the object code ...

Hi All Quote from the LPC17XX manual - "IAP commands, which result in a FLASH write/erase operation, use 32 bytes of space in the top portion of the on-chip RAM for execution. The user program should not use this space if IAP flash programming is permitted in the application." Does anyone know which space is being referred to exactly? The LPC1766 which I use for tests has three SRAM banks: ...

Hi, I'm working on a project with a lpc 2148. I've written a program which reads from the serial port a text file. I save the characters of this file in an array: buff[2000]. Now I'd like to write this array to the flash of the lpc2148. But I've a few questions about this operation. - Is it possible to overwrite the bootloader of the lpc2148? When I write accidently to the wrong sector, I...

I am using Olimex LPC-P2148 board and its OCD debugger in my application development . I intend to use unused flash as substitute of any external EEPROM . As my application demands maximum five write operation during whole lifetime of application . This data will be read only 99% of time . Using flash will save chip cost , board space , fault rate and its rectification cost etc . I do not see any ...

I'm experiencing write failures of a bit in flash. If I write the pattern 0xA55A to a location like 0x1DC10 and then write a vector to the following location, 0xDC14, I find that the first location has become 0xA558. Now let me explain the write algorithm I'm using. I ne

Hay Guys, I have been trying for over 2 weeks to get a definitive answer from NXP technical support regarding this question... When CPR1 is set is it possible for the processor to use the boot loader to save data to the flash memory? That is, when my code needs to save operational parameters to the processors flash memory can this be done by the processor itself, (IAP), if the CPR1 bit is s...

I have a firmware upload feature that works most of the time (SD card to Serial Flash to CPU Flash). It still fails occasionally, however. I have noticed that the binary file that is created by the ELF tool (which is loaded onto the SD card) is NOT the same as the code loaded by Keil uVision thru the JTAG. It differs at the very end of the code space (up around 3BE00) for the last bit...

That's the whole point. With JTAG you would be able to read the FLASH or download a new program that can read the FLASH. So that would defeat read protection! All you can do is erase everything by in-system programming over the UART. But. If you want to debug your own code that has read-protection enabled, you can set bit 2 in PINSEL2 as an early step in your code. This will switch P...

I have 'successfully' uploaded new code from my SD card to CPU flash through my intermediate flash. I have my secondary bootloader at 0x00000000 and my app at 0x00004000. Everything uploads and verifies correctly to 0x00004000. However, after the WDT trips, the transfer to 0x00004000 doesn't work like it did before. I erased sectors 4-23 on the CPU leaving the bootloader and the vector table. ...

Hi! Maybe someone with experience on IAP could give me some guidelines? I'm having quite a hard time with writing to flash (IAP) in my program. I am using LPC2388 and my application needs to download lots of stuff from UART and write that into into flash. I am using GNU tools. My application is receiving 512bytes at a time from UART and saves that into a uint8 buffer[512]. Once buffer is fu...
