MakeitC won't write to PROstart

[Pompey2]

Bruce - I have programmed this board using this setup many times before. But I just downloaded the newest version of MakeitC [11.00] and when I compile code it runs ok until it tries to download the hex file to the chip. Then I get:

Code: Select all

Blinky4 is 13.65K code  1.37K data

CPU = 1114, Flash Map = 1751
C:/CORIDI~1/MAKEC1~1/CPFILE~1/Blinky4.hex 13664 bytes loaded
Can't open COM-Port \\.\COM7 ! - Error: 5

The chip is still running an earlier program, so I don't think it's fried? Just can't load new code.
Can't change the chip as it's soldered in.
Have I forgotten a step somewhere?

Thoughts?

Edit: The cpu ID is correct according to Table 386 in the /user Guide LPC1114FN28/102 0x0A40 902B; 0x1A40 902B

I have seen this intermittently on my HP Netbook (which is a slow machine).

It seems like Windows is not releasing the serial port very quickly on that machine (and yours as well). So I added some delay in MakeItC which is running IDlpc to check the CPU type and then LOADlpc to do the download (both open and close the serial port).

As for the CPU ID, the high order nibble is different from what I see in the DIP28 version or the TSSOP28 versions of the LPC1114.

I'm building a release with that delay in the MakeItC load process. (should be there about 11:30 today)

As indicated, the NXP manual shows both x0A and x1A for the top byte. But I don't think I've EVER seen that error msg before?

Any chance you can make just the changed function available to avoid having to do the uninstall-download-install waltz for a second time today ? My ISP is running dog slow and keeps stopping all together - must be the snow, again!

Replace these 2 files, the changes should close the serial port more quickly.

That did it - thanks!
