答复: flash_rom start and size

For example, 1. I only want to let end user to flash normal part [0-384k), and don't let him touch fallback part [384k, 512k). 2. or I only want to update the payload image in the beginning, [0,64k).

You should prepare the image the same size as your flash chip. There are techinical difficulty doing this. Most flash parts are block/sector erase and byte program. There is no general way to start from an abitrary address to any size. Ollie > Regards > > YH >

Otherwise I got them just once (coming just from via the list). Honestly i found this sole system enough, what is more some message I believed to be not interessing to me (after reading) appear to be relevant later on : maybe it's because i'am a rookie :) mathieu

Sorry, I've lost track. Has anyone here tested EPIA VGA? Does it work? I've just gotten a request for an EPIA with VGA running Filo. ron

It could only process 64k block.

Program up to the limit of the file size or the flash size, whichever is small. This was for partial programming. flash_rom s <start block #> <lenght in blocks> program using stdin as the data, starting at start block # and for length blocks OR eof on stdin, whichever was smaller. This was pretty handy for the DS10, which had 2 MB of flash in 64KB blocks, and had areas of flash we could not rewrite. maybe we need this for the general case? ron

In the PMC pm49fl004, You got eight 64K size blocks. You can erase the individual block and write that block only.

You need to back up some part of the erase block you want reserve , erase the block and write with updated and reserved data. You probably need MTD.

flash_n_burn rom utils, /dev/bios ... resquest
by Mathieu Deschamps 21 Apr '04

21 Apr '04

Hello, I was wondering in what measure it would be possible to read/write a bios via a LPT port. If i am not mistaking, every flashing facility solution reads/writes a onboard bios chip. I know this could sound very strange to you. Also, I know how difficult it is to handle request that steps aside of what the system is meant to do. But I don't feel confident with bios hot plugging... I've read this is a sensible operation and well ... Mainly i couldn't afford to "break" my unique build machine bios ! I'd rather like to make a backup copy of my bios in another chip and then to cold plug this copy to work with Linuxbios. Has anyone felt this worry . How come could I resolve this ? thanks in advance mathieu

FILO --> zelf format to reduce size to 32k below.
by YhLu 21 Apr '04

21 Apr '04

Eric, Can you add something in filo Makefile and make it produce zelf format? If the size to be 32k below, for fallback boot the payload could be FILO+Etherboot --> [384k, 416k](FILO) + [416k, 448k) (Etherboot) , instead of putting the Etherboot in the [0,64k) of ROM, and FILO in the [384k, 448k). Regards YH
