Public bug reported:
Writes to UART 2 and 3 disappear. As a sanity check I put printf
statements in the function stm32f2xx_usart_write in
qemu/hw/char/stm32f2xx_usart.c and recompiled qemu. The result confirmed
text sent to UART1 and UART4 are sent to that function while text sent
to UART 2 and 3 are not. I assume writes to all 4 need to make it to
that function for emulations to operate correctly.
Example code that writes to all 4 UARTs/USARTs (does not contain the printf
statements mention above):
