(or until you press a key at the serial console, which causes an RXĪlso once a character has been written, it waits for a TXEIE interruptīefore sending the next character in a string. however at the outset TXE is clear, so it blocks forever It checks to see if the TXE bit is set before trying to write anyĬharacters. Interrupt to let the OS know the channel is now empty and it can send again.ĬhibiOS depends on the correct behavior of the TXE and the TXEIE interrupt.

QEMU STM32 DRIVER

OS driver code unmasks this bit and TXE is set, this should trigger an Have to wait for the appropriate bits to be written to the I/O pins.Ģ) Implement support for the TXEIE (TXE interrupt enable) bit in CR1. Qemu_chr_fe_write_all() right away and unlike real hardware we don't This is because we dump each character to The way this model works, the FIFO isĮffectively always empty. The two changes are:ġ) After wrtiting to the data register, don't clear the TXEīit in the status register.
