Field Documentation

log_rd_idx

volatile uint32_t app_log_cpu_shared_mem_t::log_rd_idx

Init by reader to 0

log_wr_idx

volatile uint32_t app_log_cpu_shared_mem_t::log_wr_idx

Init by writer to 0

log_area_is_valid

volatile uint32_t app_log_cpu_shared_mem_t::log_area_is_valid

Init by writer to APP_LOG_AREA_VALID_FLAG. reader will ignore this CPU shared mem log until the writer sets this to APP_LOG_AREA_VALID_FLAG

log_cpu_sync_state

volatile uint32_t app_log_cpu_shared_mem_t::log_cpu_sync_state

CPU sync state

log_cpu_name

volatile uint8_t app_log_cpu_shared_mem_t::log_cpu_name[APP_LOG_MAX_CPU_NAME]

Init by writer to CPU name, used by reader to add a prefix when writing to console device

log_mem

volatile uint8_t app_log_cpu_shared_mem_t::log_mem[APP_LOG_PER_CPU_MEM_SIZE]

memory into which logs are written by this CPU
