EvgeniK45 Posted June 10, 2016 Author Posted June 10, 2016 Ok, I'm asked and I'm answering! I found driver source file of watchdog, and comment the line which spammed to message file. Here it is: pr_info("%s, write reg 0x%08x\n", __func__, (u32)&wdt_reg->ctrl); static int wdt_restart(void) { #ifdef WATCHDOG_DBG if(NULL == wdt_reg) { pr_err("%s err, line %d\n", __func__, __LINE__); return -1; } #endif //pr_info("%s, write reg 0x%08x\n", __func__, (u32)&wdt_reg->ctrl); writel((0xA57 << 1) | (1 << 0), &wdt_reg->ctrl); return 0; } I recompiled the core and the problem solved. I hope this information will be taken into consideration when creating new system images...
