I knew it nikolaus get these stages wrong and youll end up with mismatched corruption on the phone,,probably corrupting all future installs.<br />how efficient are the resets?Does the gta04 have a reset facility?<br> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr" > <font size="2" face="Arial"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Dr. H.

> <BR>> I started with a GTA04A4 with empty Flash and a newly bought 16GB SD-Card Class 10. I reformatted the SD-Card manually because I wanted to get practice. So I called "fdisk" and set up 255 "heads", 63 sectors and 1947 "cylinders" (-> Why on earth is this necessary on an SD-Card??).<BR><BR>Some technical background:<BR><BR>The OMAP processor has a Boot-ROM that knows how to find a binary block of data on a specific position of a SD card. I.e. it does not really know about file systems, but about a "raw" access.<BR><BR>To enable us to mount and copy files into a file system, but make it be stored at the specific position on the SD card, needs to format it in a special way and copy the file MLO as the first one.<BR><BR>Dhe Boot-ROM can load it into SRAM (64 kByte on Chip RAM). The MLO code loaded into the SRAM is a stripped down U-Boot. But that U-Boot knows about the FAT file system, and can therefore load u-boot.bin from any location on
the SD card (as long as it is in the FAT partition).<BR><BR>By the way this is the reason why the file is called "MLO". It is MMC LOader. (MMC ~ SD). Because it comes through the MMC interface and loads U-Boot from there.<BR>There is also X-Loader which loads U-Boot from NAND flash. And it is intended to be flashed into a specific position in NAND flash so that it can be found by the Boot-ROM as well.<BR><BR>Nikolaus<BR><BR>_______________________________________________<BR>Gta04-owner mailing list<BR><a ymailto="mailto:Gta04-owner@goldelico.com" href="mailto:Gta04-owner@goldelico.com">Gta04-owner@goldelico.com</a><BR>http://lists.goldelico.com/mailman/listinfo/gta04-owner<BR><br><br> </div> </div>
