-> I have developed the STM32F105RBT6 development board, when I had flashed the USB host-related program into it using STLink, the program is flashed into it, but shows verification failed. After that, I had retry to flash the ic but ic is not detected by ST-Link Utility
-> Also I will try to flash the ic using UART but the same issue
Now how to solve these issues, is there any basic configuration I am missing. ? please help me.
Connection for ST-Link :
uC connection
PIN46(PA13) - SWDIO
PIN49(PA14) - SWCLK
PIN7 (NRST) - 10K->3V3
PIN60(BOOT0) - 10K -> GND
Connection for UART :
uC connection
PIN42(PA9) - RX (of USB to TTL)
PIN43(PA10) - TX (of USB to TTL)
PIN7 (NRST) - 10K->3V3
PIN60(BOOT0) - 10K -> 3V3
