Congrats! Sounds like you have your system working. I unfortunately tried replacing my eMMC and it seems I ended up pulling some of the pads, or at least that�s what it looks like to me. These things are so damn small I have no idea how you would even start to repair them if even possible.

As a last ditch effort, I did order a NAND flash TSOP package (MT29F32G08CBADBWP-12IT:D TR) just as a hope and a prayer that it would function the same as the eMMC. But I�m highly doubtful. I�m about 99% sure that if I could have swapped the eMMC it would have worked. It kind of stings to feel to be this close and something silly happens like this. But I guess it is what it is.

I�ll report back if the TSOP package works but since someone else here already tried it...i am doubtful.

Hi,
I checked the pinout for the said chip, and have a lookout for the seven unpopulated pads near the text U_NAND.
Seems like they are connected to pins 4-6 (these are NC according to datasheet), 10 (NC), 12 (VCC!), 14 (NC) and 15 (NC).
There might, or might not be, power supplied to the chip? there's a VIA on the chip side, so it might have power. Worth checking though.

So the working one will crash within lifecycle controller for some reason, but other than that it works. I will try to reset/clear NVRAM etc.

Not looking at the time debugging, but taking it apart, in-place-dump emmc, fetch the enterprise-license, desolder emmc, solder emmc, but it all back together and verify if it works or not - this will take 2-3 hours.
Debugging is another thing, and the purchase of parts and supplies that I didn't have from before. Was it worth it, as replacements are available for ~200e on eBay? depends on how you value your time.

Taking debugging, file digging (for the license) into account - not to mention if a reball is required on the new emmc - a LOT of hours were spent.

Also, as bootleg license CAN be bought for as much as ~33e on eBay, how much is your time worth digging THAT info?

No dice on using the TSOP :(. I put a TSOP memory package on and I get the same error.
```
iDRAC7=> mmcinfo
sh_mmcif: Cmd(d'1) err
Card did not respond to voltage select!
```

Anyone know if there is a switch to make the switch to using the TSOP? I tried to short a couple of the jumpers I saw around the NAND/MMC chip but no dice :(. Same result as above. Without have a diagram of the board I don't think there is anything else I can do.

Right. I changed the eMMC on a failed R630, but it does NOT attempt recovery from SD-card. Here's the console output:

What format is your SD-card (fat/fat32/ntfs/ext4)?
What did you write to the SD-card?
You are working with a Dell R730, this thread is mostly about R720 or Rx20 family machines, so I do not know if the R730 has the sd recovery stuff in it, or if any requirements about getting it to do image recovery have changed.

Hello All! I replaced eMMC on my DELL r720 twice, but u-boot and mmcinfo say "Card did not respond to voltage select!". What can be wrong? I tested eMMC with external programmer, they are good. When I replace it, i do not prepare new eMMC, just soldered it on the motherboard. May be I should copy partition from original emmc? eMMC is same model (H26M31001FPR).

Card did not respond to voltage select! -> it's not completely soldered on board.
Be sure to preheat the board as well

I soldered with preheat, same result.

May be I need fwu update command?

Looking at your console log its defanitly having issues talking to your emmc chip, this line: sh_mmcif: Cmd(d'1) err is certainly fatal when it is trying to initialize the emmc. Do you know what this all looked like before you tried to replace the chip?

alucard666 the before replacement shows that it probed the EMMC and found it fine, but later had read errors. The after replacement can not even find the device any longer, so something went rather wrong with your chip replacement is about all I can conclude.

Hi,

I've been reading through this thread a couple of times and found it again everytime I was looking up the error message I've got. So far you have already helped me a lot with the console. Maybe you can help me out or put the final nail in the coffin of my R720xd I just got for free.

Thanks to you I am able to access the console. This is what I get.

I've seen messages in this thread that look like this error, but I don't get a timeout for instance, it just loops.
I am able to reboot using the SW_IDRAC_DBG pads A1-B1, but I can't abort the boot using A2-B2.

Is there a chance iDRAC can be fixed?

@vqu you should poweroff and unplug the system from power, short a2/b2 and leave them shorted, then power on the system. See if that gets you to uboot prompt. I can tell from your messages you appear to have a rather serious mmc problem. Has some rework attempt been done to this board?

I just powered the server with A2 B2 shorted, no change. The output is exactly the same.
I was the first one to do anything to the board when I soldered the UART pins. It was running for 1994 days when I shut it off due to a failed iDRAC.

@vqu is there an SD card in one of the slots? If so try to remove that. To me these message look like maybe an sd card is failing to init.

There is a vflash SD card in the back of the server and two cards in the idsdm module. The message stayed the same no matter what card I removed or swapped. Even removing the idsdm module didn't change anything.
