kann mal jemand mit toshiba chipset bitte orig booten
dann telnet:
./unspare2/dev/mtd1 /tmp/oob.img

Sie müssen registriert sein, um Links zu sehen.

enptacken und nach /tmp vorab schieben und chmod 755 drauf. dann o.g. ausführen.
des erzeugt ein oob.img mit 328bytes.
des bitt ma raren/taren und hier anhängen.

edit: das wird aber auc nix bringen denke ich.

Failed to decode NAND READID [98 dc 90 15]
No NAND device found!!!

Wenn 0x98 und 0xdc klar sind, was ist dann noch mit 90 15. Die müssen wohl auch noch vom kernel verstanden werden, oder?
Ich meine die komplette READ ID vom Chip muss verstanden und entsprechend gesetzt werden.

A NAND-based Flash memory chip returns in response to the Read ID command several data bytes (identifier).
 The most frequent identifier type is 4 bytes long, but it can be longer as well. 
 Identifier structure:
 Byte 1 describes the chip manufacturer (Vendor ID).
 Byte 2 describes the memory chip itself as a device (Device ID).
 [COLOR=#ff0000]Bytes 3–n[/COLOR] describe in vendor-specific format the settings of the  internal memory chip structure including memory page size, memory cells  type, presence of several segments, etc.

Sorry, ich würde ja gern mithelfen. Aber ich komme erst am Wochenende wieder an die Box ran

So, hier mal die erste Info (Spark gebootet, Ausgabe mittels dmesg, kein Comcable Logging):

NAND device: Manufacturer ID: 0xad, Chip ID: 0xdc (Hynix NAND 512MiB 3,3V 8-bit)

Bild kommt gleich.

en comlog wäre nützlich von evo boot ob da auch 90 15 kommt.

@neuss,
2 seiten vorher schreibst du du hättest auch toshiba ram?
und da bootet evo am pinguplus bei dir?

Meine Box hat auch den Toshiba-NAND verbaut:

falls dem so is kann ich nämlich hier aufhören zu suchen denn dann haben die user wos nich geht schlicht defekte hw-chipse was bei edision ja eigentlich standard is!

AW: Evolux for Pingulux ext. yaffs2

Ja, ich habe Toshiba-NAND und nein: Evolux und ProtoluxV3 booten nicht bei mir.
Das oben ist das dmesg von Sparks.

Das "[98 dc 90 15]" ist aus dem BootLOG vom Evo mit anschliessender Kernel-Panic.

Was sagt denn ein Bootlog vom Evo, das auch fertig bootet?

So weit ich noch weiss:
Viprex Plus Kiste hat Hynix und läuft mit EVO
DIVIDIS Plus neue Kiste hat auch Toshiba und bootet EVO auch nicht zuende.

 

[pinky1981]

AW: Evolux for Pingulux ext. yaffs2

ok.
hab ma in mei heimatboard angefragt ob da jemand noch was weiss.
wenn des nix wird bliebe nur noch en evolux als jffs2 bauen und für die "geschädigten" zur verfügung stellen was dann natürlich einiges langsamer booten wird.

 

[neuss67]

AW: Evolux for Pingulux ext. yaffs2

Und ich werd mich mal noch ein wenig weiter in die Materie einlesen. Vielleicht finde ich ja noch einen Hinweis.

Das "[98 dc 90 15]" ist aus dem BootLOG vom Evo....

Also die Zahlenfolge?

 

[neuss67]

AW: Evolux for Pingulux ext. yaffs2

Bei Dir steht:
NAND device: Manufacturer ID: 0xad, Chip ID: 0xdc (Hynix NAND 512MiB 3,3V 8-bit)
Also (0x)ad (0x)dc und nix weiter
Manufacturer ID = ad für Hynix
Device ID= dc

Das [98 dc 90 15] kommt vom Toshiba-Nand, womit der Kernel aber nichts anfangen kann und daher ausgibt; Failed to decode.

Falls sich jemand da einlesen möchte, der aber bessere Linux-Kenntnisse als ich hat:

I am able to successfully flash and boot using a Micron  MT29F4G08ABADA NAND WP Flash chip, which seems to have the same specs  and technology as your target chip.  I am able to program the device  installed in the i.MX28 EVK NAND flash socket over the micro USB  connector link from a Windows PC running the Freescale Manufacturing  Tool.  I am then able to boot the EVK from NAND flash to load a custom  Linux kernel and UBIFS root filesystem.
Getting the NAND chip to  be recognized during the kernel boot scan and programming the chip via  the Mfg Tool are independent operations, and both must be successful.   Since the output you sent is generated from running the Mfg Tool,  perhaps you should start there and continue until the programming is  successful.  Then, you can move on to getting the EVK to boot from NAND.
I  have compared a capture file of output from the debug terminal during a  successful Mfg Tool programing run with yours  I have not looked  exhaustively, but our outputs track very closely except for the NAND  chip-related items.  The critical difference begins at line 106 in my  file:  "Scanning for NAND Flash chips...".  Interestingly, during your  run, the next line ("NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda  (Micron NAND 256MiB 3,3V 8-bit") shows that your NAND chip was detected  and the ID's were read correctly.
I believe the Mfg Tool  "updater_ivt.sb" kernel uses the same technique to recognize NAND flash  types as works in the "normal" kernel.  The first step is to locate the  device in the following array of structures:
    struct nand_flash_dev nand_flash_ids[ ],
which is initialized in the following kernel source file:
    [ drivers/mtd/nand/nand_ids.c ]
Your chip ID (0xDA) matches the following entry:
[COLOR=#008000]    /* 2 Gigabit */[/COLOR]
    {[COLOR=#A31515]"NAND 256MiB 3,3V 8-bit"[/COLOR], 0xDA, 0, 256, 0, LP_OPTIONS},
whereas my chip ID (0xDC) matches the entry in the next size block:
[COLOR=#008000]    /* 4 Gigabit */[/COLOR]
    {[COLOR=#A31515]"NAND 512MiB 3,3V 8-bit"[/COLOR], 0xDC, 0, 512, 0, LP_OPTIONS},
This matching is how you received single "NAND device:..." output line in your file.
The second step is to locate the device in one of the arrays of structures of the following type:
    struct nand_device_info[ ],
which are initialized in the following kernel source file:
    [ drivers/mtd/nand/nand_device_info.c ]
There  are a number of these arrays of structures, corresponding to different  "Types", as shown in the following "directory" from the same file:
/*
* A table that maps manufacturer IDs to device information tables.
*/
    static [COLOR=#0000FF]struct[/COLOR]nand_device_type_info nand_device_type_directory[] __initdata = {
        {nand_device_info_table_type_2, [COLOR=#A31515]"Type 2"[/COLOR]},
        {nand_device_info_table_large_mlc, [COLOR=#A31515]"Large MLC"[/COLOR]},
        {nand_device_info_table_type_7, [COLOR=#A31515]"Type 7"[/COLOR]},
        {nand_device_info_table_type_8, [COLOR=#A31515]"Type 8"[/COLOR]},
        {nand_device_info_table_type_9, [COLOR=#A31515]"Type 9"[/COLOR]},
        {nand_device_info_table_type_10, [COLOR=#A31515]"Type 10"[/COLOR]},
        {nand_device_info_table_type_11, [COLOR=#A31515]"Type 11"[/COLOR]},
        {nand_device_info_table_type_15, [COLOR=#A31515]"Type 15"[/COLOR]},
        {nand_device_info_table_type_16, [COLOR=#A31515]"Type 16"[/COLOR]},
        {nand_device_info_table_bch_ecc12, [COLOR=#A31515]"BCH ECC12"[/COLOR]},
        {nand_device_info_table_bch_ecc24, [COLOR=#A31515]"BCH ECC24"[/COLOR]},
        {0, 0},
    };
In  the same file there are functions and logic that locate a particular  entry for a specific NAND flash chip.  In my case, my chip is matched to  the following entry:
/*
* Type 7
*/
static [COLOR=#0000FF]struct[/COLOR]nand_device_info nand_device_info_table_type_7[] __initdata = {
< snip >
    {
        .end_of_table = [COLOR=#0000FF]false[/COLOR],
        .manufacturer_code = 0x2c,
        .device_code = 0xdc,
        .cell_technology = NAND_DEVICE_CELL_TECH_SLC,
        .chip_size_in_bytes = 512LL*SZ_1M,
        .block_size_in_pages = 64,
        .page_total_size_in_bytes = 2*SZ_1K + 64,
        .ecc_strength_in_bits = 4,
        .ecc_size_in_bytes = 512,
        .data_setup_in_ns = 20,
        .data_hold_in_ns = 10,
        .address_setup_in_ns = 10,
        .gpmi_sample_delay_in_ns = 6,
        .tREA_in_ns = -1,
        .tRLOH_in_ns = -1,
        .tRHOH_in_ns = -1,
[COLOR=#A31515]        "MT29F4G08AAA"[/COLOR],
    },
< snip >
};
This  table is the source of critical information regarding the NAND  geometry, timing, etc. that appears in the debug terminal listing when  the chip is successfully recognized during the kernel scan.
The matching function for Micron devices in the same file begins with the following:
static [COLOR=#0000FF]struct[/COLOR] nand_device_info * __init nand_device_info_fn_micron([COLOR=#0000FF]const[/COLOR]uint8_t id[])

 For  my chip, there is an entry in both the "Type 2" and "Type 7" arrays  that would seem to match, but the matching function returns the "Type 7"  entry.  Your chip seems to appear in the "Type 2" array, but is missing  from the "Type 7" array.  Since our chips are very similar and seem to  use the same technology, I would expect that the would be of the same  "Type".
So, your chip appears to fail to match a  "nand_device_info" structure.  I believe that the table used in the  "updater" code that runs as part of the Mfg Tool uses the same tables,  which would explain the failure to recognize your chip.  It appears that  your next step must be to add support for your chip within the context  of the Mfg Tool.
Once your chip is recognized, the other major  issue you will face is deciding what type of flash filesystem to use.  I  am successfully using UBIFS, but JFFS2 is also a widely-used choice.   You will have to make that decision following your own requirements and  criteria.

Nachtrag:
Der Hynix NAND ist ONFI-Nand und scheint damit keine Extended Parameters zu brauchen, dem reichen Hersteller- und Device-ID.
Das ist beim Toshiba nicht so einfach, der muss dem System klar seine Parameter mitteilen, also 0x90 und 0x15.

AW: Evolux for Pingulux ext. yaffs2

nand_device_info.c gibt es nicht und auch im gesamten kernelsource is kein nand_device_info zu finden
das is auch nicht das problem.
der code an sich passt.
man muss zu allererst die exakte chip-typenbezeichnung des toshiba wissen. und die steht nunmal auf dem chip selber drauf.
sowas wie: TC58NVG3S0F
erst dann kann man da ran gehen.
warum bei dir unspare2 nicht geht kann ich nicht nachvollziehen.
hab hier gmTriplex gebootet-orig der auch toshiba chip hat und da gehts!(fw 1.2.54)

kannst auchmal statt "mtd1" mal "mtdblock1" versuchen.
