i2c 异常之i2c1 prob 检测超时

在没加atl 的fpga 时 i2c1上的tvp5150 vpss驱动加载没问题，

加了之后出现超时

I2C: timed out in wait_for_bb: I2C_IRQSTATUS=1000

/*
* PSP_i2cCreate should have been called for this instance
* for its proper initialization.
*/
if(gVps_deviceObj.i2cHndl[i2cInstId] != NULL)
{
for (slaveAddr = 0x5c; slaveAddr < 0x5d/*128*/; slaveAddr++)
{
if (PSP_i2cProbe(i2cInstId, slaveAddr) == 0)
{
Vps_printf (" I2C%d: Passed for address 0x%x !!! \r\n", i2cInstId, slaveAddr);
}
}
}

 

只加载5150的i2c 后可以通过
