I have read several threads where new ARM programmers like myself have encountered a problem where their code (custom board) only runs when using the debugger. I have yet to find my problem. I have programmed two other ARM boards using the LPC2101 chip with problems. This board using the LPC2131 is somehow different. The JTAG interface has pulldown and pullup resistors. The emulator sele...


Speed Problem on LPC2300 & LPC2101/2/3

We have identified a speed problem affecting the LPC2101/2/3 and the LPC23xx series. This speed path interferes with instruction fetches, limiting the operating frequency to approximately 60 MHz. However, this issue is code and code-position dependent, which is why the issue was not immediately apparent in testing . Many customers' code executes at full speed without any issues. It h...

Greetings all (new to the LPC20xx and to this group) I'm trying to make some sense of the intended migration path for some of these micros. Based on what I've read, the LPC2101/2/3 are newer parts than the LPC2104/5/6 and are the upward migration path for those parts... The LPC2101/2/3 seem to be *mostly* pin-compatible with the 4/5/6 parts (except for pins assigned to some extended featur...

Only one of them had a HW problem, the other were OK. ...
