Flash Magic has no control over what the bootloader returns to it.

However, assuming there is a problem erase and program errors can be detected by using the CRC feature in the LPC9xx to make sure what you programmed matches your hex file.

Hi,

I have seen in ISP code (LPC_ISP_8K_V04.a51) than after calling an IAP function (from bootrom) checks the F0 flag to indicate whether an error has occurred. But the user manual of the 89LPC932A1 (UM10109) specifies the Cy flag to indicate an error when using IAP. To be sure of that, I have read and disassembled the bootrom code and I can confirm that Cy is the flag used. So, due this bug, does this mean that FlashMagic has no control of whether is an erase/program error occurs?

Best Regards,

Valenti

PD: I found another bug in bootrom code. The "Progam User Code Page" can use IDATA (F1=0) or XDATA (F1=1), but after program only checks with IDATA. So, if you use XDATA, even with a succesful programming, always you get a verify error (VE). But this does not affect the ISP as this only uses memory IDATA.

I did and just as I was starting to compare the working waveforms to the non-working, they started working!
Disconnected the scope & it still works!?!

I'm guessing that somehow in testing all of the options (T1, T2, times for instance) that some of the settings didn't get returned to their proper state.

All is well now. Thanks.

We have tested Flash Magic with Windows 7 64-bit and haven't seen any problems ourselves. If you are dependent on DTR and RTS then I recommend you put a scope on those signals to see how they are behaving.

Update: tried to fix this by changing the Compatibility Mode to "Run this program in compatibility mode for: Windows XP (Service Pack 2)".
Did not work.

We have an in-house designed programming board that uses RTS & DTR to ISP several of our products that use the 89LPC932A1. There's been no issues with it until recently. I just "upgraded" to a new PC that has Vista-64 versus the old PC that ran XP Pro. The problem is, now FM doesn't work with the on-board serial port, or the add-in serial card (Rosewill RC-301)! It gives the dreaded "autobaud" failure message.

I can take the programming board connected to the product board over to the old PC and check the Device Signature as a quick test, with no problem. I've scoped everything out on the new PC and it looks like there is some strange timing issues between RTS & DTR, irrespective of which port I try. I did download and install the latest driver for the Rosewill card, but to no avail. I have the latest FM: 5.69.2060.

So has ANYBODY programmed an LPC9xx part using the RTS/DTR method under Vista or Win 7? (We tried it on the IT guy's PC with Win 7 and if failed there too).

Note: I have programmed an LPC1114 with the same new PC and FM with no problems, but of course, this does not use the same interface as an LPC9xx.

Thanks.

To clear the DCCP bit you need to use either ICP or parallel programming. You can't do it with ISP.

The NXP ICP bridge is a microcontroller running firmware that converts from RS232-based ISP commands to low level ICP signals.

Dear Sir:

How to recover it to be unckeck in ISP operation? or anyother way?
What's the meaning of "NXP ICP BRIGDE" in interface option?

 Hi,
We have problem about IAP in P89V51RD2. I have flashing the below code HEX file to P89V51RD2 chip. After reset the chip, the chip again not going to programming mode. I am not able to re-flash again. Please give me a solution. I am attaching the code here.
flash magic prompted a red message "reset the device into isp mode now"!!
