BSP fails to build for FreeRTOS on a Nios V with UART

I have a Nios V on a Max 10 with a UART (RS-232 Serial Port) Intel FPGA IP (and also JTAG UART). When I opened up the BSP editor, I selected FreeRTOS and went with all the defaults and made a BSP. Ho...

    In the "freertos/drivers/src/":

    if (sp->tx_start == ((sp->tx_end + 1) & ALT_AVALON_UART_BUF_MSK))

    ALT_UART_WRITE_RDY,

    ALT_FLAG_SET);

    }

Hi,


I am a bit caught up on my side, I will try to get the test in the next few days.


Thank you for your patience, I shall get back to you soon.

"On-Chip Flash Intel FPGA IP" doesnt compile either:

In file included from freertos_bsp/drivers/src/altera_onchip_flash.c:32:

    I've experienced this one as well. The reason is that the do {} while(0) is surrounded by a brace due to the macro expansion in altera_onchip_flash_regs.h

    You can fix it by modifying each of the macros altera_onchip_flash_regs.h and removing the outermost brackets like so:

    Old:

    #define ALTERA_ONCHIP_FLASH_ENABLE_WRITE_AND_ERASE_OPERATION(base)              \
    (                                                                           \
        IOWR_ALTERA_ONCHIP_FLASH_CONTROL((base),                                \
            (IORD_ALTERA_ONCHIP_FLASH_CONTROL((base))                           \
            &                                                                   \
                ~(                                                              \

    @EBERLAZARE_I_Intel Can you flag this to be patched as well? And any news on when the UART fix will be submitted? This is affecting me also.
