I am trying to setup the STM32F3 CW308 target board to use a much faster clock (e.g. 48MHz).
I did the following steps:
- Change the constants in the HAL (
SystemCoreClock, return values of
HAL_RCC_GetPCLK2Freq) to 48MHz.
- After flashing, but before connecting to the target I set the
clkgen_freqto 48MHz and wait for the ADC to lock.
- Connect to the device, with SimpleSerial, trying both UART baud rate of 38400 or 115200 (changed both in the HAL and on CW side for the 115200).
However I get no data on the UART line.
Is there anything elso one has to do to change the frequency of the STM32F target boards?
