Got problem about get_free_int get interrupt

Postby z43740979 » Wed Nov 01, 2017 8:57 am

When i init SD card or i2s it works,but when use it together,got a interrupt conflict,get_free_int return like this
SDcard retrun 18 then i2s return -1 , only init i2s get_free_int return 18. How to solve this conflict
[0;31mE (11829) intr_alloc: best = 18[0m
[0;31mE (11849) I2S: i2s_isr_register[0m
[0;31mE (11849) intr_alloc: best = -1[0m
[0;31mE (11849) I2S: TAG = 0x105[0m
[0;31mE (11849) I2S: Register I2S Interrupt error[0m
