Hello, I'm using lpc21isp to program my LPC2106. When I try to download the test2 hex file from the Aeolus newlib example, I get the following output: (...) Writing Sector 0: ....(...) Sector 0 written Writing Sector 1: ....(...) Sector 1 written Writing Sector 2: ....(...)...Wrong answer on Prepare-Command (2) (Sector 2) CMD_SUCCESS ...and the program doesn't work (no traffic on TXD). If I change "#if 1" to "#if 0" and vice-versa (to disable the UART echo example), the program loads ok, and I can receive the "hello world"-message over the UART. What's wrong here? Thanks Andreas |

I tracked down the error message. It's coming from this piece of code sprintf((char *)tmpString, "P %ld %ld\r\n", Sector, Sector); SendComPort(tmpString); ReceiveComPort(Answer, sizeof(Answer)-1, &realsize, 2,5000); sprintf((char *)tmpString, "P %ld %ld\r\n0\r\n", Sector, Sector); if(strcmp((const char *)Answer, (const char *)tmpString) != 0) { printf("Wrong answer on Prepare-Command (2) (Sector %ld)\n", Sector); OutputErrorMessage(GetErrorNumber(Answer)); exit(4); } The prepare command is documented as taking a start sector and an end sector number and so something like P 2 2 should be sent to the micro. Unless echo is turned off then that should be echoed back followed by the return code number (which should be 0 for CMD_SUCCESS). It's apparently not getting that but the code is converting whatever is received to a number and then to an error message. If you can compile the code try inserting the following line printf("Expected [%s] -- Received [%s]\n", tmpString, Answer); That may help track down what is actually happening.

If so, does it work? I just tried it, works perfectly. |

OK, that narrows it down to the download program which is probably a simpler problem. Consider the debug print I suggested. Martin, do you want to jump in here?

Yes, i can reproduce the problem on my PC. LPC sends me "P 2 2 RESEND", so i think the last transmitted block is wrong (fill block...).

I'll leave it to Martin for the moment to fix. At least you can use the Philips Utility as a work around. Robert " 'Freedom' has no meaning of itself.
