From b8f9d706673769b43c390eef1b34bb589da6643b Mon Sep 17 00:00:00 2001 From: JF Date: Fri, 19 Jun 2020 22:11:21 +0200 Subject: Use PRIMASK instead of BASEPRI for critical sections in FreeRTOS. This is needed by NimBLE to be able to mask radio interrupt (which has priority 0). --- src/FreeRTOS/portmacro_cmsis.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/FreeRTOS/portmacro_cmsis.h b/src/FreeRTOS/portmacro_cmsis.h index 3d2dee5c..0497538f 100644 --- a/src/FreeRTOS/portmacro_cmsis.h +++ b/src/FreeRTOS/portmacro_cmsis.h @@ -106,8 +106,8 @@ extern void vPortEnterCritical( void ); extern void vPortExitCritical( void ); #define portSET_INTERRUPT_MASK_FROM_ISR() ulPortRaiseBASEPRI() #define portCLEAR_INTERRUPT_MASK_FROM_ISR(x) vPortSetBASEPRI(x) -#define portDISABLE_INTERRUPTS() vPortRaiseBASEPRI() -#define portENABLE_INTERRUPTS() vPortSetBASEPRI(0) +#define portDISABLE_INTERRUPTS() __asm volatile ( " cpsid i " ::: "memory" ) +#define portENABLE_INTERRUPTS() __asm volatile ( " cpsie i " ::: "memory" ) #define portENTER_CRITICAL() vPortEnterCritical() #define portEXIT_CRITICAL() vPortExitCritical() -- cgit v1.2.3
