Hi, Is there a way to do a software reset in the LPC17xx chips? I wrote a USB bootloader and I would like a way to enter the bootloader from the main firmware without the user having to manually do something on the board. I guess one option might be to simply reset the program counter back to 0x00? Thanks, Moses ------------------------------------

Hi, I download the USB Secondary ISP Bootloader example for LPC2148 to use for Keil MCB2140 board at http://www.standardics.nxp.com/support/documents/microcontrollers/zip/an10711.zip The bootloader works as an USB Mass Storage to upload the user application into flash by copy and replace the firmware.bin. It works fine on window PC when I copy my binary file to replace firmware.bin. Aft...

Can someone point me at sample /open source code for lpc213x bootloader that branches to FW update or normal C main at startup? I found lots of discussion in the archives, but no example code. Thanks, Jay

Does anybody know if there's any existing USB Bootloader for LPC2148 devices or similar to it? Basically, I want to download/update firmware via USB instead of ISP or JTAG. I already tried TNKernel "Firmware Upgrader", but didn't work as expected. Any help is much appreciated. Thanks in advance.

Hello, I am so newbie in this world, that I have read many post related to bootloader and I have an idea about how to solve my problem but I do not have clear how to implement it. I am using a LPC2220, Keil compiler and a JTAG. I have the program "Mybootloader" at 0x80000000. This program at certain time jumps to another program "Application", which is at 0x80010000. Both are independent, an...

Hello, I am just starting work on an LPC2468 based board and wanted to know how I could best develop for a future flashless design. I want to use the 2460 when I go to my end system. I realize that the onboard bootloader will behave different because of this. So on my internal flash if I had a secondary bootloader that jumped to my external memory bank1, would this mirror the effect ...

I wonder how to use the Olimex LPC2148 board - it only has USB connector and no RS232. A virtual com port based bootloader would be nice. I'm not considering JTAG.

Hi, I'm working with an LPC2131 in the Keil compiler. I've made two projects, a bootloader project and a main application. I want to make use of a shared variables to have the two apps communicate with each other. I'm able to create a variable on a fixed address using the following code: TE_SHARED shared __attribute__((section(".ARM.__at_0x40000000"))); So both applications read an...

Hello all, I just posted (in the files area: lpc_host_tools.tar.gz) some code I wrote to support file upload and bootloader interface to the LPC on linux. I did this stuff a few months ago so I don't totally remember everything about it, but its pretty simple and should be able to be

For reference the posting we did on Dec 22 ---- 1) Am I right in assuming LPC2000 CRP is a software fence implemented in the supplied boot loader code? Partially. It is a combination of Hardware and Software supplied in the bootloader code. Application running in micro has full access to the entire memory space. 2) I am going to replace

I am trying to use the sill bootloader program with a usb dongle on com4 and step 4 of the instructions seems ok except the board is a IAR kickstart with 12.00 xtal and it says 11.67. If I try the time ./sill etc as shown below, it doesnt work. If I just enter time and enter, it does show the time. I am not sure how to proceed. I don't seem to be able to get the NITE program to run with m...

Hi I'm trying to create a secondary usb bootloader in a LPC1768 based on CodeRed example for RDB1768. The difference is that my version need to have 2 files. One file is the main program that is going to boot and the other is a user file, which contain only data. I've managed to create a FAT12 partition that shows me the 2 files, the problem is that when I try to delete the...

I've apparently trashed by bootloader and am having a tough time getting back to where I can talk to my Keil 2140 board serially. I've been playing around for a week now with sample Keil code examples getting familiar with how things work and connecting and uploading and downloading fine. It was going very well until I got brave and uploaded a sample piece of my own code. The board locked

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. ...

Can anyone offer some clarification on the bootloader pin on the LPC23xx. Pin P2.10 appears to have a pullup activated on reset. Do I need to pull this up again? I see in the manual: Pin P2.10 that is used as hardware request for ISP requires special attention. Since P2.10 is in high impedance mode after reset, it is important that the user provides external hardware (a pull-up resistor ...

Hello Everyone, I am working on porting my LPC2366 bootloader to the LPC1768. Right now I am having a problem when calling the main application. First of all I check the vector checksum of the application. If the checksum is okay the main program is called. I managed to get the main application to build and run from 0x8000 when using the JTAG by offsetting the vector table and using differe...

I know very little about the arm controller of lpc2000 series. can any one suggest idea for making use of in built boot loader available in lpc. I have studied that lpc 2000 series has got built in boot loader and it is activated when Port 0.14 will go low. I want your advice and the procedure to make use of bootloader for ISP.

Hey guys I'm currently working with a 2458 and I'm running into some issues with setting the device into bootloader mode from a host machine with both lpc21isp and Flash Magic. I've dropped in a jumper to allow the MCU to be reset via the serial port. I'm now seeing two issues; When I connect to the board via the serial port with either putty or minicom (The latter from a Linux guest VM on a...

Hi! I finded interesting Application note: Ethernet secondary ISP bootloader for lpc23xx and lpc24xx. http://www.nxp.com/acrobat_download/applicationnotes/AN10744_1.pdf I didn't find any example or application that is mention in document. Did anybody find it? Bye Peter ------------------------------------

The earlier LPC2xxx ARM processors require a bootloader update in order to protect the code from being read through ISP. We created a free update tool that is suited to reprogram any number of LPC2xxx microprocessors quickly and fool proof. The update tool provided by Philips works just fine, but only for engineers and the update job is quite tedious.
