STM32 USART error

[newfag]

Hello!

I need your help. I decided to upgrade to the latest version of your operating system, as necessary DNS support. In the previous OS version my project worked. Now, when the device is started ( debug module with stm32f427) get the message -

"Embox kernel start runlevel: init level is 0 unit: initializing embox.driver.serial.stm_usart: error: Operation not supported Failed to get into level 1, current level 0"

I do not know what is the problem here .

Configuration file in attach.

Thanks!

Hi,

Try to change include embox.driver.char_dev_stub to include embox.driver.char_dev_old

But I have not STM32F4 board now and can't check another parameters. It's better if you switch to a new default configuration template for stm32 (arm/stm32f4cube). It includes a new drivers (uart and  ethernet) and supported several ttyS in singe configuration.

Except this, I found include embox.driver.audio.stm32f4_pa_test in your configuration, Is it really needed for you?

Regards, Anton

Hi,
Now i have message - 

"runlevel: init level is 0

        unit: initializing embox.driver.serial.stm_usart: error: No such entity

Failed to get into level 1, current level 0"

I'll try to go on HAL and use your new templates.

Hi,

I think the fast way to resolve your problem is to comment following line:

return uart_register(&stm32_uart0, &uart_defparams);

in 'stm_usart' driver and return 0 instead
