Hi all,

well I got putty dailed in and shorted pin 2 to pin 2: shorting pin 2 to 2 on SW7 did not seem to make any difference at all. This is what we read in putty:

all in an infinite loop. As you can see we do not get as far as others...

Dead EMMC chip?

I am thinking at buying an EMMC reader, or a SD card I can put 2.54mm pins on as the grab pins do not really grab on well to my sdcard reader

Is connecting pin2 to pin 2 on SW7 correct for the T620?

unfortunately still no luck -- followed all the steps and this is what I see on the last command:

iDRAC7=> bootm
Wrong Image Format for bootm command
ERROR: can't get kernel image!

So I attempted the same steps but instead of using 1.66.65 I tried 2.10.10 (and also 2.21.21), and now I get a slightly different error (even after rolling back to 1.66.65):

try these:
tftpboot firmimg.d7
fwu mmc sd
fwu check 0x81000000
fwu update 0x81000000
saveenv
go 0x81000000 #this is important !

then you should have something in your /dev/mmcblk0p2
edit it in a linux, repalce 'mmcblk0 ' to 'mmcblk1' in some scripts

put the sd card back into your r720

then run these:
set fwummc sd
bootm

you may need to reboot several times using 'bootm' command

The above worked for me, except for the very last command I had to use `boot` not `bootm.

I think "set fwummc sd" should be "fwu mmc sd"

I also added

1
 
sentenv verify no

before the saveenv command.

saveenv
go 0x81000000 
 

Eject sd card and take it to a linux machine, unless you have usb passthrough it'll likely have to be a physical machine.

lsblk

sudo unsquashfs /dev/sdb2
sudo grep mmcblk0 unsquashfs-root/etc
#Edit each file to change references for mmcblk0 to mmcblk1
sudo vi squashfs-root/etc/sysapps_script/S_3160_create_scratch.sh
#etc.
sudo squashfs squashfs-root /dev/sdb2 -noappend
 

Insert the card into the iDRAC.

fwu mmc sd
boot
 

My 4-GB SD card was very slow. Waited a long time for the sd card parittions to format

There are references to mmcblk0 in binaries, such as /bin/dellutil, a hex editor could fix those.

The next boot failed, but I did

1
2
3
 
fwu mmc sd 
saveenv
boot
 

Again my sd card was very slow and took a long time at the MASER images.

My display was unlit after it got to "Please press enter to activate this console", but pressing the front panel idrac buttons got the display to light up.

Currently booting doesn't work automatically for me, I have to `fwu mmc sd` `boot` but I'm still working on it. Each boot takes 3-5 minutes.

Right, I ordered an EMMC reader to make sure it reads. I did not trust my cheap SD card reader. In the mean time if any of you have any things to try out or ideas, I am all ears.

I do not get to the stage where shorting pin 2 matters. Not even with a FAT 32 formatted SD card.

For reading the EMMC, you can do this with the board powered off right?

It should be pin 2 (of 2nd group) to ground

Patiently waiting for my UART adapter to turn up, its onboard for delivery, was hoping to get it today before the long weekend so I could see what is going on.

Hey guys, finally got my UART to USB adaptor, I've soldered it to the motherboard but I don't seem to be able to connect via COM3, my PC is seeing the UART to USB adaptor on that port. Will I need to change to COM3 on the R720 for it to be able to connect? Also, when looking at the UART adaptor it only has a solid red light for GND, should TXD and RXD both have lights?

Do I need to short the interrupt UBOOT and if so what is the best way to do this, do I just use the solder copper, ignore my ignorance as I'm a soldering noob.

Only 3 of the 4 need to be connected, yes. Not sure which one is RX/TX, I usually experiment swapping back and forth until something appears on screen

Where there any other settings that need to be set aside from the speed 115200, data or parity etc? I've tried to use Tera Term and it just sits on a blinking screen and not picking anything up. I've tried swapping the txd and rxd with no luck.

@natharas looking at your log, I see:
display_factory_info.sh[3915]: 2.63.01.60.62
I am concerned that due to the iDracula vulnerbility it is not possible to interrupt u-boot any more. I am not sure if you can down grade to a version that allows interrupt.

I further note that I do not see any failure in your boot log, but the log does not appear to be complete.

Sorry, I've been preoccupied with some other things so this got put to the side. Out of curiosity, when you set the Serial connection up, how long should it take before it starts getting data from the iDrac?
