i find this LPI2C_DRV_MasterSendDataBlocking can't used under freertos task,
read is always return 2, seems when write i2c is always busy, can anybody help to check it ?
i2c_test11,TMF882X_STAT=0
tmf882x_i2c_write ret=0
tmf882x_i2c_read,fisrt ret1=0,second ret2=2,recv=0
BTW, when use without freertos i can read i2c slave data correctly.
int test_tmf882x_i2c_read(uint32_t slave_addr, uint8_t reg, uint8_t *buf, int len)
{
//return read_i2c_block(slave_addr, reg, buf, len);
int ret1,ret2;
ret1 = LPI2C_DRV_MasterSendDataBlocking(INST_LPI2C1, ®, 1, false, I2C_TIME_OUT);
ret2 = LPI2C_DRV_MasterReceiveDataBlocking(INST_LPI2C1, buf, len, true,I2C_TIME_OUT);
AMS_TOF_LOG("tmf882x_i2c_read,fisrt ret1=%d,second ret2=%d,recv=%d\n",ret1,ret2,*buf);
return ret2;

if(len == 1)
send[len] = *buf;
