Read-Only Author Mohammad Adel Posted 26-Jun-2004 07:37 GMT Toolset C51	Programming the chip Mohammad Adel Is it true that some programmers require the hex file records to be arranged in ascending order according to their addresses? I faced a problem with a programmer, the software stopped writing to the chip at a certain line and gave an error. There was no problem with the hex file ( I used a simulator which takes the hex file as input, and it worked properly) Thanx..

In fact, it may still be true, but I haven't heard of this on any contemporary programmers. Note that this is not a requirement of the Intel HEX specification. If needed, the following knowledgebase article tells how to sort HEX records. http://www.keil.com/support/docs/1236.htm Jon

Software doesn't usually fail in different ways if you repeatedly do the same thing with it. It's rather more likely that your hardware (either the programmer itself, or the chip you're trying to (re)program) is flaky.

Read-Only Author Mohammad Adel Posted 2-Jul-2004 06:26 GMT Toolset C51	RE: Programming the chip Mohammad Adel I don't get the question. What do you mean?

I don't get the question. What do you mean? The programmer require you to enter the chip you are programming. do you enter the chip you are programming or another derivative because your programmer does not have an entry for the chip you are using? Rephrase: what chip are you trying to program? what do you enter into the programmer software as the chip it is to program? Erik

Read-Only Author erik malund Posted 2-Jul-2004 14:20 GMT Toolset C51	RE: Programming the chip erik malund The programmer automatically detects the chip and its type. Which programmer? Does it come back and tell you which chip (it thinks) it is programming? I have found that the most unreliable thing about programming uCs is reading the device ID, I guess I click 'ignore' on "wrong device ID' one time out of 3. Erik
