Subject: [U-Boot] i2c_reg_read() on 8xx
Date: Wed, 22 Oct 2008 14:36:47 -0500 [thread overview]
Message-ID: <48FF80CF.3070209@freescale.com> (raw)
Wolfgang,
Mike Frysinger helped me resolve the problem with i2c_reg_read() on Blackfin, so
I'll be posting a new patch soon. However, I noticed that 8xx has a problem, too:
uchar
i2c_reg_read(uchar i2c_addr, uchar reg)
{
uchar buf;
i2c_init(CONFIG_SYS_I2C_SPEED, CONFIG_SYS_I2C_SLAVE);
i2c_read(i2c_addr, reg, 1, &buf, 1);
return (buf);
}
Is the call to i2c_init() necessary on 8xx boards? Shouldn't I2C have already
been initialized?
