ChibiOS Free Embedded RTOS

Thank you so much for help! In new version (2.6.5) is UART4 already defined.

This is a part of my mcuconf.h: /* * UART driver system settings. */ #define STM32_UART_USE_USART1 FALSE #define STM32_UART_USE_USART2 FALSE #define STM32_UART_USE_USART3 FALSE #define STM32_UART_USE_USART6 FALSE #define STM32_UART_USART1_RX_DMA_STREAM STM32_DMA_STREAM_ID(2, 5) #define STM32_UART_US...

Hi Giovanni!

(STM32F407)
Is possible use an UART Driver for an UART4 peripheral? I can run the UART4 with SerialDriver, but the SerialDriver is not good for RS485 mode.

Is there any way how to run UART4 peripheral with UART Driver?

Thank you!

Hi! I had this problem: My Backup SRAM lost data randomly when power connector was unplugged. I finally found the solution of this problem and I would like to share the problem solution here. For a long time I was looking for a problem in the configuration and init of the backup domain. Then I tried...

Ok, so when I enable option of debug checking of any subsystem to TRUE, system is automatically halted although it is only a warning?

I am using debugger from STM32F4-discovery board (wired to my board) + OpenOCD + Eclipse. How can I print debug messages on screen?

Hi all! Is possible debug ChibiOS over serial? I mean - every assert, exception or warning write on serial link?If it is possible, can you tell me how to enable this feature? I found only Eclipse plugin, which I´am already using. And second question - Can I watch states of memories? How much the mem...

I have already found my mistake... A setted up the MAC filter too early than I could. For others: Disable MAC filter after initialization of network stuffs. Disable MAC filter near before using netconn_recv.

Hi all! I can´t get to work multicast communication. DHCP is already working. AUTOIP is unwanted. Problem: err = netconn_join_leave_group(conn2, &mcast_addr, &thisif_ptr->ip_addr, NETCONN_JOIN); still waits for semaphore. Nothing is catched. My steps for IGMP config: added into lwipopts.h: /...

It seems the problem is solved! The problem was in a bad use netbuf buffer. This is WRONG: static struct netbuf *recv_buf; recv_buf = netbuf_new(); netconn_recv(conn_ctrl_recv, &recv_buf); This is CORRECT: static struct netbuf *recv_buf; netconn_recv(conn_ctrl_recv, &recv_buf); Conclusion: D...
