Am posting this in case anybody come across same issues. 1.OMAP MMC code keep throwing "Pbias Voltage is not same as LDO" error continuously. Balaji is planning post right fix for the same, but just in case you get around this issue, reg = omap4_ctrl_pad_readl(control_pbias_offset); @@ -158,7 +159,14 @@ static void omap4_hsmmc1_after_set_reg(struct device *dev, int slot, OMAP4_USBC1_ICUSB_PWRDNZ_MASK); omap4_ctrl_pad_writel(reg, control_pbias_offset); /* 4 microsec delay for comparator to generate an error*/ - udelay(4); + timeout = jiffies + msecs_to_jiffies(500); + do { + reg = omap4_ctrl_pad_readl(control_pbias_offset); + if (!(reg & OMAP4_MMC1_PBIASLITE_VMODE_ERROR_MASK)) + break; + mdelay(1); + } while (!time_after(jiffies, timeout)); + reg = omap4_ctrl_pad_readl(control_pbias_offset); if (reg & OMAP4_MMC1_PBIASLITE_VMODE_ERROR_MASK) { pr_err("Pbias Voltage is not same as LDO\n"); 2. can't open /dev/ttyO2: No such file or directory This is not obvious console entry missing problem in FS.
