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!

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!

LPC932 hasn't support ICP :puzzled:

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!

When the beginning, I load the exam Hello to micro, no matter happen. But then, when I want reprogram micro  using ISP again, it isn't work. I try some ways , but haven't result. Please for me any advice!
Thanks before!

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)

Hi Andrew!
I'm using P89LPC932-CB6765-T10246 C, the ISP point is 1E00H or 1E03H? I config: BSB=1, BOE=1, RBE=1, but micro can't enter ISP again after send Start Bootloader <89LPC932AppNote>.
I'm using Flash Magic Ver2.52
Thanks before!
