ok. thanks
And where can I find a Boot software programmer for PC? I'm using STM32 ST-link utility but it hasn't ''a serial programming mode''2011-05-17 05:20 AM
I program one chip with a firmware. Into this firmware there is the JTAG Disable command ('' AFIO_MAPR=0x4000000; ''). Now How can I erase the chip? Is it possible re-use this chip with ST-LINK debugger?
No, you're going to need to use the serial port method, selecting the system memory with the BOOT pins. You could also in the future implement a back door method to re-enable the JTAG, or erase the chip, from within your application.2011-05-17 05:20 AM
