S912XEQ512在烧录过程中出现 FP：No Programming Voltage，芯片不能烧录，可以被解密
I would like to ask you to communicate in English. you will probably get more supporters.
now; from your description is not clear what is wrong. This is translation from translator: "Hello Gentlemen teacher, recently encountered a problem, ask for help! FP S912XEQ512 appear during recording: No Programming Voltage, the chip can not burn, can be decrypted"
Probably, If the MCU was working previously I predict it could be secured. In order to unsecure the device you can use more ways:
1) Only to be sure the MCU is running: Check clock; Start MCU in the special mode MODC=MODB=MODA=0. You should see BUSCLK=OSCCLK/2 at the pin PE4. 2)
Unsecuring the MCU:
1) By application SW, the unsecuring feature or backdoor key must by implemented in user’s application.
2) Another way how to unsecure the device is to use unsecure command from CodeWarrior debugger or unsecure program from www.pemicro.com pages.
If you use USB multilink you have to use unsecure Option MultilinkCyclonePro->Unsecure in the CodeWarrior Hiwave Debugger.
or you can use external usecure program which can be downloaded from pemicro pages.
