P89V51RC2FN can't erase all Flash or block used by hex file issue

[pmax65]

I already read about this problem in other posts in this forum, but I don't have found the solution.
I can't erase the whole Flash or the block used by the hex file using the P89V51RC2FN with FM.

Does anybody solved the issue?

I know, I can erase the whole MCU by [ISP] > [Erase Page...] > [Erase All], but anybody knows why doesn't the blocks erase work?

May be, is it an ISP command bug?

Bye,

First try upgrading your bootloader as this sounds like a past problem that was solved in an update. You can get the new bootloader from the resources section of the Flash Magic website. Be sure to follow all the instructions.
