My customer complained that our Mcu(ADUC7020) Do Not work . When I checked it, I found that the mcu work in Bootloader,the 0x80014 HAVE Been erased!!! For update my Firmware conveniently,I designed a function which can erase the 0x80014 to 0XFFFFFFFF. So when the mcu power up,it will go directly to Bootloader(The i2c device address is 0X04) .This funciton need a highest password,the customer do not have the password. This question
puzzled me for a few days.
