Hi,
i bought some Nucleo F103RB Boards and designed a circuit board for the Nucleo to drive my LEDs throught Bluetooth.The prototype with airwires worked perfectly, but know i tried it with my circuit and if i plug the Nucleo on my circuit i got strange behaviour in flash sizes.If i try to flash an image it cannot verify.st-link showed my everytime i run it a different flash size, the sram and page size kept.Here is a sample output:2014-10-14T10:04:07 INFO src/stlink-common.c: Device connected is: F1 Medium-density device, id 0x200364102014-10-14T10:04:07 INFO src/stlink-common.c: SRAM size: 0x5000 bytes (20 KiB), Flash: 0x20000 bytes (128 KiB) in pages of 1024 bytes2014-10-14T10:04:07 INFO gdbserver/gdb-server.c: Chip ID is 00000410, Core ID is 1ba01477.2014-10-14T10:04:07 INFO gdbserver/gdb-server.c: Target voltage is 3269 mV.2014-10-14T10:04:10 INFO src/stlink-common.c: Device connected is: F1 Medium-density device, id 0x200364102014-10-14T10:04:10 INFO src/stlink-common.c: SRAM size: 0x5000 bytes (20 KiB), Flash: 0x3fffc00 bytes (65535 KiB) in pages of 1024 bytes2014-10-14T10:04:10 INFO gdbserver/gdb-server.c: Chip ID is 00000410, Core ID is 1ba01477.2014-10-14T10:04:10 INFO gdbserver/gdb-server.c: Target voltage is 3264 mV.2014-10-14T10:04:44 INFO src/stlink-common.c: Device connected is: F1 Medium-density device, id 0x200364102014-10-14T10:04:44 INFO src/stlink-common.c: SRAM size: 0x5000 bytes (20 KiB), Flash: 0x2020000 bytes (32896 KiB) in pages of 1024 bytes2014-10-14T10:04:44 INFO gdbserver/gdb-server.c: Chip ID is 00000410, Core ID is 1ba01477.2014-10-14T10:04:44 INFO gdbserver/gdb-server.c: Target voltage is 3271 mV.Anyone got the same strange behaviour of this? I dont know where it belongs to.Greetings Michael #nucleo-f1032014-10-17 12:50 AM
Ok, i figured it now out with your helpings. It was the Flash latency time like you said.
I use now openocd to flash the nucleo board with no problem. The texane's st-link utils aren't stable enough for the f103rb.Thanks for your helpings 🙂
