Hi Erik!
I'm sure that security bit is not set!
FlashMagic:
ISP --> Read Security --> Display: 'Security Bit 1 unset'

Hi!
Thanks to BTDN because of your suggestion! But it seems so complicated when we must erase all flash pages ̣(ISP-->Erase Flash pages-->Select all pages) before reprogramming!
Could you give any advices to solution this prob?
Thanks before!

P89V51Rx2/P89LV51Rx2 / Problem with P89V51RB2FN
September 05, 2006, 09:20:04 AM
Hi Andrew!
I'm using P89V51RB2FN.
Manufacturer  ID: BF
Device ID: 91
When using FlashMagic to program, I met prob same Benoit at: http://www.esacademy.com/software/flashmagic/forum/read.php?f=1&i=2725&t=2725
So, I do something as your suggestion. It has no problem in the first time!
But, when reprogramming, FlashMagic can't verify the code. And when I select:  (ISP)erase flash- then (ISP) Display memory, the first code is no change in flash!
What happen with my chip?
Thanks before!

Thanks to Andrew!
1. LPC932 RevC isn't support hardware Reset. (3pules RST) I can programe ISP with LPC922 using harware reset and have no problem.
2. I config micro BSB=1, BOE=1, RBE=1, in Start900.a51. I see that by this way, micro can enter ISP again after sending Break Condition, but micro isn't work as I want.
Maybe I try to using ICP.
Thanks again!

To Andrew!
Flash Magic UM said that:   "If a break condition is sent, then Flash Magic does not expect the break condition to be echoed back and assumes the device has been placed in Bootloader mode." and: "Once the device completes the reset the Bootloader will be executed, allowing the device to be reprogrammed."
I do so:
1./ Connect to PowerSuply
2./ P1.5 = 0
3./ Open FlashMagic , click ISP, Start BootLoader-->Send Break Condtion-->Start BootLoader
4./ Click ISP-->Device Signature

Flash Magic alert: Unable to connect at the specfied baud rate. Try reducing the baud rate. Reset the hardware into ISP mode again.
Please for me advice! Thanks before!

I had read section 6.10 and example kstartbootrom.uV2, but, I had loaded the example Hello (Keil\C51\EXAMPLES\Philips LPC9xx\Hello\) into micro.  And in this project, I disable all interrupts! What happen with it?

To Andrew!
I'm reading UM from link: http://www.semiconductors.philips.com/acrobat/usermanuals/UM_P89LPC932_1.pdf
I can't see section 6.10 as you say, maybe on pages 112-115, but I  haven't  result from it,  P89LPC932 verC hasn't  support for hardware Reset!
I do all thing like this: http://www.lpc900.com/pdf/enter_isp.pdf (page 1). Please for me any suggestion!
Thank a lots!

To Andrew!
Thanks for reply!
I can't have any affect  to micro when using Start Bootloader Command. Flash Magic alert:  Operation Failed. (Start BootRom Command-no echo)
