[U-Boot] AM335x Boot Device 6 (NAND?)
Hi Tom, we have equipped some of our am335x boards (draco from mainline U-Boot) with NAND devices from Hynix. And as it seems, the BootROM passes now a different bootdevice number to SPL. Its not 5 as it used to be for NAND but 6 instead. So SPL hangs of course as this boot-device is not supported. Could you please let me know what this boot-device == 6 means / represents? Should it be handled identical as the normal NAND boot-device (5)? Just to make this clear. This is the code that I'm referring to: arch/arm/cpu/armv7/omap-common/boot-common.c: /* * rom_params can be type casted to omap_boot_parameters and * used. But it not correct to assume that romcode structure * encoding would be same as u-boot. So use the defined offsets. */ gd-arch.omap_boot_params.omap_bootdevice = boot_device = *((u8 *)(rom_params + BOOT_DEVICE_OFFSET)); BTW: U-Boot can handle this Hynix NAND (same layout as the other NAND chips we use) without any problems.

Well, my guess is that you've wired it up, or at least selected SYSBOOT pins saying that this is a NAND+I2C device where the geometry is stored on an i2c eeprom (see 26.1.7.4 of the TRM). Is this really what you wanted is my first question. :) -- Tom signature.asc Description: Digital signature ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
