SDK 12.0.0 nrf_drv_uart compile error

[Sébastien Le Ray]

Hi,

I think there's an error in SDK12's nrf_drv_uart, some code parts unconditionally use p_instance->reg.p_uart (eg. nrf_drv_uart_task_address_get, interrupts_enable) whereas its definition depends on UART enablement. Either the definition should be unconditional (at a first sight p_uart maps p_uarte correctly) or code should be conditional.

This result in build error with following settings

#define UART_ENABLED 1
#define UART_EASY_DMA_SUPPORT 1
#define UART_DEFAULT_CONFIG_HWFC 0
#define UART_DEFAULT_CONFIG_PARITY 0
#define UART_DEFAULT_CONFIG_BAUDRATE 30801920 // 115200
#define UART_DEFAULT_CONFIG_IRQ_PRIORITY 6
#define UART0_CONFIG_USE_EASY_DMA 1

Regards

Hi

I acknowledge this bug and can reproduce it just by setting

#define UART_LEGACY_SUPPORT 0

in sdk_config.h in the default ble_app_uart example in SDK 12.0.0.

Below is the SDK 12 ble_app_uart example with modified nrf_drv_uart.h and nrf_drv_uart.c which include a fix. The two modified files are placed in the project folder. It seems to work properly but please let me know if you dont find it adequate.

I've to say I'm quite disappointed by Nordic… nothing in release notes and the corresponding support case is still open…
