Fixed the problem myself :o) It was when writing the configuration to the mode register in the SDRAM, the 256MB device i had the code from used (logically) 12 ...
Hello from a group newbie = ) I got myself a brand MCB2360 board recently and have played around with it for some time now but when my curiosity turned towards...
Re: [lpc2000] Re: SD Card read/write using SSP in Keil's MCB2140 (MCU LPC2148) Dear Joel, I have done some test on EFSL but I would like to try also Chan ...
Hi, I try to explain a little bit more detailed. LPC stores self generated bitmaps in external dataflash or on a SD Card. The uncompressed datstructure is...
Depending on how your images look like a RLE-compressed BMP might be a solution for you. It is not effective as GIF or PNG are, but it is much easier to...
Hi, All ISP commands are supposed to have <CR><LF> at the end. In some LPC2368 versions (especially those mounted on MCB2300 boards), there is some bug with...
... Yes, the read-modify-write behaviour of bitfields means that you wouldn't use a bitfield member for access of a write-only register. The use of the union...
Hi Friends, My project is based on LPC2368 controller and Iam using GNU compiler alongwith the Keil uVsion3 IDE. I would like to know the donwload link for...
Hi I'm using this on my LPC2148 and it works fine so far: I'm flashing in chunks of 512bytes. Don't forget to turn off IRQs! clock = 60Mhz static char...
I need to detect a debug break in the core execution from software. My reason for this is not security; it is for debugging the non- realtime part of the...
Hello All: I face a problem, I use LPC2468 chip and I use RTX os, after I start the system, the program will jump back to reset handler. who have any ideal to...
I wrote my own Flash Utility. After writing the entire Flash I read it for check, but I found errors in first 64 positions. Anyone know if I'm having a common...
I wrote my own flash utility also and discovered that the 1st 32 bytes after the vector table would be corrupted after the ISP operation was completed. So now...
LPC2148, bootloader version 2.11. After a watchdog reset takes place, I am unable to enter ISP mode after setting the BSL jumpers, and pressing reset. The...
There's nothing in the core I know about that would allow you to detect this, but you could use some memory location that gets set by your debugger on debug...
... Check section 21.4 of the User Manual. "If P0.14 is sampled low and the watchdog overflow flag is set, the external hardware request to start the ISP...
jcwren Wrote ... There is memory retained of whether the last reset was due to a watchdog. The BSL line is ignored in that case. It's possible you have to...
I believe I have found the cause for the problem with programming flash. The LPC2103 requires the clock to be coupled in via a 100pF cap and not, as I have...
The first 64 bytes starting from the address 0x0 are mapped to the bootloader area in ISP mode. You should map vectors from the user flash area by writing 0x1...
... I think this has something to do with remapping of the exception vectors. This is a feature of the LPC series of chips that allows you to (for example) put...
Yah, thanks, that did the trick. I overlooked that statement about the watchdog flag in section 21.4, and it was not crystal clear that the WDTOF flag was...
Hi there, The sample codes for lpc23xx is for Keil's Real View Compiler. But, there is no startup.s file available with respect to GNU Compiler. ... [Non-text...
... Just a thought, is the watchdog enabled? If yes, you need to service it. Also, if you use the DMA, the service of the watchdog must not be interrupted...
Hi again, : ) Right, I forgot to include: ISP version is 1.3 I have no problems at all once synchronized, all commands works like a charm. Well, I go for your...
Hi all, I am using the Keil MBC2100 dev. board, (LPC2129), and the Rowley Crossworks dev. system, (GNU tools). So far, so good. The IDE, compiler etc. is err.....
Hi Friends, Iam using LPC2368 controller for my project and I need to store both RAW and Filtered CAN data in the in-built Flash memory of the controller. ...
