Are you getting any other IRQs through the twl4030 code? There's not a lot of debugging I can do with this, since I don't have an EVM ... and since this seems to work OK on other boards. (Testing on SDP being easiest, since it's got a slot not tied down with MMC root.) This patch was basically sent as a seed, since nobody else seemed to be filling in the missing MMC/SD pieces on that board. - Dave > root@xxxxxxxxxxxxx:~# cat /proc/interrupts > CPU0 > 11: 0 INTC prcm > 12: 4 INTC DMA > 25: 0 INTC dispc > 37: 1724 INTC gp timer > 56: 267 INTC i2c_omap > 57: 0 INTC i2c_omap > 61: 0 INTC i2c_omap > 72: 178 INTC serial idle, serial > 73: 1 INTC serial idle > 74: 1 INTC serial idle > 83: 43 INTC mmc0 > 92: 0 INTC musb_hdrc > 93: 0 INTC musb_hdrc > 335: 0 GPIO ads7846 > 336: 3565 GPIO eth0 > 369: 0 twl4030 twl4030_keypad > 378: 0 twl4030 twl4030_usb > 384: 0 twl4030 mmc0 > Err: 0 > > Regards > Mani > > > -----Original Message----- > > From: linux-omap-owner@xxxxxxxxxxxxxxx [mailto:linux-omap- > > owner@xxxxxxxxxxxxxxx] On Behalf Of David Brownell > > Sent: Thursday, February 05, 2009 4:53 AM > > To: OMAP > > Subject: [patch/rft 2.6.29-rc3-omap-git] omap3 evm: MMC switch support > > > > Update OMAP3 EVM board support to support the MMC/SD switches, > > when used with the twl4030 based power card. > > > > Also, less usefully, LEDB as a GPIO LED ... it's on the underside > > of the board, so it's probably not very useful to most folk.
