Posted on May 17, 2011 at 12:53We have now tried a different hardware design with the same result!!! Does anyone out there actual have the bootload running in a STM32F101C8T6?
Posted on May 17, 2011 at 12:53Hi And thanks for your help. I can not see any difference on the RX signal on the scope. The 0x7f/ACK works fine. And when I download with JTAG and run my application the serial communication on the USART with the hard...
Posted on May 17, 2011 at 12:53Hello again No luck with the baud rate. Tried chaging it in small steps after first ACK from bootload. All NACK's received. Connected the MCU directly to a PC. No change: 0x7f is ACK'ed. All command's after this point ...
Posted on May 17, 2011 at 12:53Hello Yes I've checked everything with a scope. This revealed only one problem. If you just keep sending 0x7f with no delays with e.g. 38400 baud while the MCU boots the timing will be wrong. The MCU will answer but th...
Posted on May 17, 2011 at 12:53Thanks We would like to do so, but we do not download from a PC but from an embedded system. Our application runs fine, including serial communication, when we download from JTAG. But we need to avoid the JTAG for prod...
