Chip : P89LPC932BDH
ISP Tools: Keil MCB900 , FlashMagic

I can easily enter ISP mode and fucntions like blank check, erase, download are executed without errors.
However, programs downlaoded with ISP can't work correctly!!!
For example, some functions related to I2C bus or I/O ports are damaged.
Can I use CRC provided by Flash Magic or other methods to solve this problem?

thanks~

I forgot to say that My 932 uses 12MHz crystal as clock. Did it matter ?

You can use the CRC to check if the hex file programmed correctly. Simply choose Cyclic Redundancy Check from the ISP menu and select your hex file. Note that the device global CRC and top most block CRC include the bootloader, so you will need to look at just the individual blocks that your hex file occupies.
