机器运行一段时间:E8192 ASSERT_PARAM(1024 0), in rwbt.c at line 371
机器运行一段时间不定时的打印E8192后机器重启,完整的log如附件有两次重启,1次几分钟,1次3个小时。 看起来像是看门狗复位,需要spi采集音频通过蓝牙或者wifi传出,有什么办法调试吗。 搜索E8192好像在libbtdm_app.a里面, Binary file ./components/bt/controller/lib/libbtdm_app.a matches ./components/mbedtls/mbedtls/include/mbedtls/dhm.h:991:#define MBEDTLS_DHM_RFC7919_FFDHE8192_P_BIN { \ ./compon...

i2s_apll_calculate_fi2s 计算问题
i2s设置sample_rate=48000,bits_per_sample=16,use_apll=true,fixed_mclk=12288000 i2s_apll_calculate_fi2s计算得到real rate: 47999.961,如果换成循环遍历sdm的方式得到real rate: 47999.992,看起来好像好一点点,不知道会不会有实质的影响。 i2s_apll_calculate_fi2s计算: I (402) I2S: DMA Malloc info, datalen=blocksize=128, dma_buf_count=64 I (412) I2S: sdm0=...

i2s_apll_calculate_fi2s 计算问题
例如设置sample_rate=48000,bits_per_sample=16,use_apll = true,fixed_mclk = 12288000; static esp_err_t i2s_apll_calculate_fi2s计算得到真实:real rate: 47999.961 I (402) I2S: DMA Malloc info, datalen=blocksize=128, dma_buf_count=64 I (412) I2S: sdm0=2, sdm1=154, sdm2=4, odir=5 I (412) I2S: APLL: Req RATE: 48000, ...
