I got the uSart10 working, dont know why its not working with uart4. The USART10 is ok for me, so I close these question.

by debugging further, I found out, that the UART4_IRQHandler is called only once, when the UART ist setup:
rt_thread/rt-thread/bsp/stm32/libraries/HAL_Drivers/drivers/drv_usart.c:244
stm32_control()

Shoulnd this UART4_IRQHandler called each time, when msh or finsh print something?

I forgot, this is the code I copy from CubeMX to board.c. It is called direct after SystemClock_Config:

void HAL_UART_MspInit(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};

/** Initializes the peripherals clock
*/

PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_UART4;
PeriphClkInitStruct.Usart234578ClockSelection = RCC_USART234578CLKSOURCE_D2PCLK1;
if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
{
  Error_Handler();
}

/* Peripheral clock enable */
__HAL_RCC_UART4_CLK_ENABLE();

__HAL_RCC_GPIOC_CLK_ENABLE();
/**UART4 GPIO Configuration
PC10     ------> UART4_TX
PC11     ------> UART4_RX
*/
GPIO_InitStruct.Pin = U4TX_Pin|U4RX_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
GPIO_InitStruct.Alternate = GPIO_AF8_UART4;
HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);

/* UART4 interrupt Init */
HAL_NVIC_SetPriority(UART4_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(UART4_IRQn);

}

I got some progress. There seem to be some gcc or/and C99 problems with the TinyUSB package. I am now able to compile, after doing the following hacks:

  • Disable the static_assert() calls in

/home/micha/rt_thread/rt-thread/bsp/raspberry-pico/packages/raspberrypi-pico-sdk-latest/src/rp2040/hardware_structs/include/hardware/structs/usb.h
(see also here: https://github.com/raspberrypi/pico-sdk/issues/339)

Handle GCC different from other compilers:
rt-thread/bsp/raspberry-pico/packages/raspberrypi-pico-sdk-latest/src/rp2_common/hardware_base/include/hardware/address_mapped.h

ifdef GNUC

#define hw_set_alias(p) ((__typeof__(p))hw_set_alias_untyped(p))
#define hw_clear_alias(p) ((__typeof__(p))hw_clear_alias_untyped(p))
#define hw_xor_alias(p) ((__typeof__(p))hw_xor_alias_untyped(p))
#define xip_noalloc_alias(p) ((__typeof__(p))xip_noalloc_alias_untyped(p))
#define xip_nocache_alias(p) ((__typeof__(p))xip_nocache_alias_untyped(p))
#define xip_nocache_noalloc_alias(p) ((__typeof__(p))xip_nocache_noalloc_alias_untyped(p))

else

#define hw_set_alias(p) ((typeof(p))hw_set_alias_untyped(p))
#define hw_clear_alias(p) ((typeof(p))hw_clear_alias_untyped(p))
#define hw_xor_alias(p) ((typeof(p))hw_xor_alias_untyped(p))
#define xip_noalloc_alias(p) ((typeof(p))xip_noalloc_alias_untyped(p))
#define xip_nocache_alias(p) ((typeof(p))xip_nocache_alias_untyped(p))
#define xip_nocache_noalloc_alias(p) ((typeof(p))xip_nocache_noalloc_alias_untyped(p))

endif

This is just a dirty hack, but at least, it compiles. Maybe the TinyUSB package maintainer set some flags, that the GCC/C99 problem with Pico(RP2040) get fixed.

I am still very new to RT-Thread. It seems, I forgot "pkgs --update" after selecting tinyUSB in menuconfig. So I did the update, then start scons again.
Give a lot of error messages:
