The "hwecc4_infix" is -- as you deduced -- intended to support the ROM boot loader (RBL) as it loads the second stage loader into the on-chip SRAM. Once that code is in SRAM, it'll set up the PLLs, DRAM, etc ... and then read the main bootloader (e.g. U-Boot) into DRAM. The second stage bootloader I've seen from TI expects to use that same "hwecc4_infix" for that code too. Which is rude, since it means you won't for example be able to use U-Boot to replace itself. Don't use the oob_softecc with DaVinci unless you're not ever going to use the hardware ECC; the ECC is different. Don't use the oob_softecc_kw with anything except the specific Marvell Kirkwood chips which need it. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
