Hello, Looking at the information that is out there, it is clear that people are using OpenOCD with the LPC3180. I have looked for an OpenOCD config file but have not had any luck finding one. Through trial and error I did come up with one that appears to work but I suspect that there are errors in at least the jtag scan chain section of the config file. My set up: - Linux development PC...

I set about learning how USB works, and managed to put together a CDC-ACM device. (I thought I'd be able to do a cleaner, more flexible implementation than LPCUSB, but mine turned out to just be different. Perhaps there isn't any clean way to do USB -- it's just a complex, stateful, highly-interconnected mess.) Anyway, my device enumerates under Linux and I can talk to it using Minicom, ...

I have three functions below that *should* do the same thing. In fact, they do the same thing on my Linux box gcc plain jane standard compiler (substitute printf for SPI_Writes). However, in EWARM, they do not do the same thing when programmed to my LPC2106. Only func3 behaves as expected. My functions are: void func1(unsigned long x, unsigned int y) { unsigned char a[3]; a[0] =...

Shalom! I have a problem in that my 3com router does not respond to my UIP dhcp discovery or request commands. I used Ethereal to log and compare dhcp requests from a Linux PC and from my prototype LPC2366 board. I could not see why I am not receiving a reply. I also tried padding the message as I read that some routers have a minimum packet size. I played with the dhcpc.c code a little rep...

Haven't seen any mention of remote NDIS on the list so far. Has anyone implemented remote NDIS, perhaps on top of the lpcusb stack in conjunction with a TCP/IP stack like lwIP ? Could be quite handy for configuring LPC devices that have USB, but not Ethernet, using a webserver on a PC or Linux box without any special drivers needed at the PC end. Is this a hopeless dream on a flash device...
