Looking at the parameter file which is repeated 5 times in the start of the nand flash (using the V1.2 example) we seem to have a dos formatted file, is this correct (android is linux) as linux normally uses just 0A'a to terminate lines, not 0D 0A sequemce, anybody have the aource to the code which reads the parameters ?

That is a raw dump. The parameter file is in the ROM as a seperate file and defines the size and offset of the ROM file for each .img or partition. It is a OD/OA file so I guess you could say it is DOS. In my development post I explain how it is setup and what it does. For some reason though I cannot find my original post where I explained it to someone 🙁 The reorganization must have left the post somehwhere other than development. In order to make my ROM I had to learn what it was doing and how. If you pull the parameter file out of my ROM and look at it, it will probably make more sense than that ram dump.
Bottom line each .img or partition setup is proceded by it size and then offset into the ROM file. For instance 0x00002000@0000000(boot), 0x00080000@00002000(kernel), 0x0004000@00082000(cache)
The number is the size@offset. So first img starts at 0 and is 2000 is size. The the next one after it starts at offset 2000 and is 80000 in size. So on and so forth.

Bob,
I'm using Linux (64bit) so I'm having to build my own tools as I understand what needs to be done. Linux is the ideal Android/Linux development environment.
This is the parameter file from your image that is written to flash after updating to v1.2. The rkflashtool is running on my pc and reading the first 20 hex (32) blocks (16384 bytes) directly from the tablets flash at address 0x0.
rkflashtool can read/write the flash over usb from the pc when the tablet is in recovery mode.
When I get the time I'll remove the carage returns (0D's), write a script to recompute the parameter file size, partition offsets & parameter crc and rewrite 5 times to the flash at block offsets 0x0, 0x20, 0x40, 0x60, 0x80.

I suspect somewhere along the line using Windowz & DOS has resulted in the parameter file being corrupted . . . I removed the carage returns and rebuilt the parameter file and re-programmed the flash and all worked well.
Well I bit the bullet and stripped the carage returms, recalculated the parameter length and crc and wrote the resulting parameter file to the tablets flas and it's booting...
Here'e the writes followed by a read of the flash and executed a reboot:[stevep@localhost v1.2]$ rkflashtool w 0x00 20 < p00rc

The parameter file in my ROM was edit in linux. In fact I learned my lesson early on not to even copy files that go into a ROM with a PC. It "touches" the files and changes them and this can make the flash not boot. Amazing...
So how did the param file get corrupted in yours?
Not sure I am understanding.

Bob,
I'm not saying you did it, it was probably done before you started modifying it. If I corrupted it the crc would of been broken and it would fail to load !
I've just taken the parameter file from your v1.2 image and sumped it with a hex dumper:

That is a raw dump. The parameter file is in the ROM as a seperate file and defines the size and offset of the ROM file for each .img or partition. It is a OD/OA file so I guess you could say it is DOS. In my development post I explain how it is setup and what it does. For some reason though I cannot find my original post where I explained it to someone 🙁 The reorganization must have left the post somehwhere other than development. In order to make my ROM I had to learn what it was doing and how. If you pull the parameter file out of my ROM and look at it, it will probably make more sense than that ram dump.Bottom line each .img or partition setup is proceded by it size and then offset into the ROM file. For instance 0x00002000@0000000(boot), 0x00080000@00002000(kernel), 0x0004000@00082000(cache)
The number is the size@offset. So first img starts at 0 and is 2000 is size. The the next one after it starts at offset 2000 and is 80000 in size. So on and so forth.

Hi BOB.
I do have a question for you. (sorry for my English in advance)
I found that my tablet is extremely slow, because of some kind bad nand/flash.
Wen I start to copy a a file (over usb from PC for example) until 2GB are passed the write speed is 300-400kb/s If 2GB are already passed/coppyed the speed skyrockets to 3-4Mb/s.
So I want to ask you, is it possible to edit the parameter file manually is such a way that I "skip" and do not use the initial lets say 4Gb.
My idea is to be something like:
Unused free space - boot - kernel- misk - data -user and so on and so on. Right now the partitions are started by offset 0.
Are you able to give me an example? here is the content of my file:
CMDLINE:console=ttyFIQ0 androidboot.console=ttyFIQ0 init=/init initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00002000@0x00002000(misc),0x00006000@0x00004000(kernel),0x0000E000@0x0000A000(boot),0x00010000@0x00018000(recovery),0x00020000@0x00028000(backup),0x00040000@0x00048000(cache),0x00400000@0x00088000(userdata),0x00002000@0x00488000(kpanic),0x00100000@0x0048A000(system),-@0x0058A000(user)
