Bob,

Does your stock OS have the same /etc/fw_env.config as Koen’s?

Hi bodhi

Yes it's the same. I was wondering if it might be a generic one, but Koen was able to read his chip after replacing the contents of fw_env.config with the Ubuntu values. The stock Ubuntu doesn't expose the mtd device. So even if I install u-boot-tools on that fw_printenv can't find it.

I spent some time yesterday looking into mtd and looking at the output of mtd_debug and mtdinfo and I don't see how the values in the Ubuntu fw_env.config file correspond to the output from those tools.

mtd_debug info /dev/mtd0
mtd.type = MTD_NORFLASH
mtd.flags = MTD_CAP_NORFLASH
mtd.size = 4194304 (4M)
mtd.erasesize = 4096 (4K)
mtd.writesize = 1
mtd.oobsize = 0
regions = 0
mtdinfo --all /dev/mtd0
Count of MTD devices:           1
Present MTD devices:            mtd0
Sysfs interface supported:      yes

mtd0
Name:                           spi0.0
Type:                           nor
Eraseblock size:                4096 bytes, 4.0 KiB
Amount of eraseblocks:          1024 (4194304 bytes, 4.0 MiB)
Minimum input/output unit size: 1 byte
Sub-page size:                  1 byte
Character device major/minor:   90:0
Bad blocks are allowed:         false
Device is writable:             true

I looked at the source code you mentioned a few posts back and the mimas board .c file has offset as 0 for the mtd device (if I'm reading that right).

That's incorrect. That code is the kernel code patch which does not have any info about boot loader. What we lack is the GPL for their boot loader version. And they also turned off input/ouput for this boot loader so we can't see anything.

That's why I said I don't know yet where is the evns location, other than what Koen posted. Can you do a hex dump for mtd to see you can guess where the envs are, or you can dd the mtd0 and upload the dump somewhere so I can take a look.

Hi bodhi

Looking at the dump in a hex editor there's a chunk of data that begins at E000 which sounds like a likely offset to me.

I've tried using these settings in the fw_env.config:
device offset:		0xe000
env. size:		0x400000
flash sector size:	0x1000
number of sectors:	400
And I get:
Read error on /dev/mtd0: Success

Bob,

I took a look. There is no envs in there that I can see.

Hi bodhi

I guess it's best to wait for Koen and see how they managed. Really all I was trying to do at this stage was to confirm the chip was being detected correctly (as you suggested it would be if fw_printenv worked).

Just got home and it is great to see that more progress has been made. Below is the dmesg output of booting with the latest dtb file. Ethernet is working and the box powers off properly as well.

Some more info about mtd. It seems the chip in my box is 8M while that in Bob's device is reported to be only 4M although that may possibly be due to different fw_env.config settings.

@Bob,

Try using the same fw_env.config as Koen's

root@debian:/etc# cat /etc/fw_env.config 
# MTD device            offset          size            erase_size

Hi bodhi and Koen

I already tried that (default Ubuntu) config. It just gives a bad CRC message.

Perhaps the dtb needs to match my spi chip? I edited the last dts with the details for my chip but couldn't figure out how to compile it to a dtb.

Let me find the sector size.

The definition in /etc/fw_env.config should be the same. Unless a different u-boot version is on Bob's box, therefore the location is different.

I'm compiling a new DTB to see if Bob can use to eliminate that SPI chip variation.

Hi bodhi

No change here:

[    1.118208] m25p80 spi0.0: mx25l3205d (4096 Kbytes)
I see in the dts you have it listed as mxicy,mx25l3205d. Searching online it came back as st,m25l3205d.

That's right, should be either st or macronix.

Here is another compilation using st.

Hi bodhi

That doesn't change anything here. Still get the same message in dmesg:
dmesg | grep spi
[    1.118180] m25p80 spi0.0: found mx25l3205d, expected s25fl064k
[    1.118196] m25p80 spi0.0: mx25l3205d (4096 Kbytes)
and the same output from fw_printenv:
fw_printenv
Warning: Bad CRC, using default environment

Hi bodhi,

do you want me to try these latest dtb files as well? I've had another response from Dell that they will chase the technical team for the uboot GPL sources of the T50.

Sure, please try the latest DTB file (good to do regression test).

Hope they will make GPL source available, that will solve the remaining issues for us. The fact that CRC error show up in Bob's box make me think there are 2 different u-boot version for T50 (Bob) and T10 (yours).

Hi Koen,

No, it is not fw_env.config. The size of the mtd is recognized by the kernel when it probes the mtd. So the mtd sizes are correct as the kernel sees. What in the fw_env.config is not the mtd size, it is the envs size. So if the envs size or the location are different, then the CRC error would make sense (this would be true if the u-boot versions are different between the 2 boxes).

This should be commented as:
root@debian:/etc# cat /etc/fw_env.config 
# MTD device            offset          env size          erase_size
/dev/mtd0               0xc0000         0x10000         0x10000

Note that erase_size is the sector size (64KB). And the total envs size is 64KB. These 2 chip types also have 4K sector erase capability. Regardless, erase size 64KB is OK here.

I've had a look through the Ubuntu sources and found this stuff related to the different SPI chips. Not sure if useful since source code is like a foreign language to me.

in ubuntu-lucid/arm/arch/mach-dove/dove-db-setup.c it mentions an 8M chip that looks a bit like the one in my dmesg log (s25fl064k )

/*****************************************************************************
 * SPI Devices:
 * 	SPI0: 8M Flash ST-M25P64-VMF6P
 ****************************************************************************/
static const struct flash_platform_data dove_db_spi_flash_data = {
	.type		= "m25p64",
};

static struct spi_board_info __initdata dove_db_spi_flash_info[] = {
	{
		.modalias       = "m25p80",
		.platform_data  = &dove_db_spi_flash_data,
		.irq            = -1,
		.max_speed_hz   = 20000000,
		.bus_num        = 0,
		.chip_select    = 0,
	},
};

while in ubuntu-lucid/arm/arch/mach-dove/mimas.c it mentions a 4M chip which matches the chip in Bobs machine. (mx25l3205d)


/*****************************************************************************
 * SPI Devices:
 *     SPI0: 4M Flash MX25L3205D
 ****************************************************************************/
static const struct flash_platform_data spi_flash_data = {
	.type           = "mx25l3205d",
};

static struct spi_board_info __initdata spi_flash_info[] = {
	{
		.modalias       = "m25p80",
		.platform_data  = &spi_flash_data,
		.irq            = -1,
		.max_speed_hz   = 20000000,
		.bus_num        = 0,
		.chip_select    = 0,
	},
};

Hi Bob,

Rename the attached DTB to dove-wyse-t50.dtb and try booting with it.

Hi bodhi

That one seems to find my spi chip ok:
dmesg | grep spi
[    1.118436] m25p80 spi0.0: mx25l3205d (4096 Kbytes)
However I still get the bad CRC message with fw_printenv:
fw_printenv
Warning: Bad CRC, using default environment
Using default values from Ubuntu:
cat /etc/fw_env.config
# MTD device offset size erase_size
/dev/mtd0 0xc0000 0x10000 0x10000

That's is actually the same as what you got before (the 2nd line where the kernel determined the right chip after the 1st message). I just want to show you the confirmation.

Hi bodhi

I just assumed that it was working better now that it didn't have the "found mx25l3205d, expected s25fl064k" line.

I meant to assure you that it works the same way regardless of that warning. The 2nd line is all we need to know that the chip was recognized correctly by the kernel.

Hi bodhi

OK, cool. It would be nice to have it working at some stage. I'd like to see if I can clean up the boot entries in the spi. I was able to edit them on Ubuntu with spi-w but they would reset back to default after a reboot. Which had me wonder if this was working right at all. Koen seemed to be able to edit them fine.

New kernel was uploaded. Please upgrade your T50/T10 box to this kernel.

The Armada DRM was configured in this kernel as module armada.

I'm not sure if the bootargs video name should be armada, but probably not dovefb anymore.

Kernel command line: rootdelay=5 root=/dev/sdb1 usb0Mode=host usb1Mode=host video=dovefb:lcd0:1024x600-16@60-edid,lcd1:1024x768-16@60-edid clcd.lcd0_enable=1 clcd.lcd1_enable=1 pm_disable titan
