LS1046ARDB - onboard mmc

[gaborkocsis]

Hello Everybody,

We have a new LS1046ARDB. There is an onboard MMC on it (MTFC4GAxxx).

My question is how can we get access for it? It doesn't appear as device either in U-Boot or Linux.

I tried all the ways that I could do based on the LS1046ARDBRM.pdf, LS1046ARDBGSG.pdf, and SPF-29142.pdf.

Thanks in advance

Hello.

My board is also exhibiting the same symptom as described by Gabor Kocsis. Following is the output of UBoot after power on. I too have tried to write the RCW in 'rcw_1600_qspiboot_emmc.bin'.

What might I be missing?

In the QorIQ LS1046A Reference Design Board Getting Started Guide it is written:

"When you boot from eMMC, you cannot insert an SD card.
If you want to boot from an SD card, insert a bootable SD card. When an SD card is inserted, eMMC will be disabled."

Isn't it your case?

[gaborkocsis]

No. I can boot from external SD card and I know that in this case the onboard MMC is unavailable. But when I boot from flash and there is no SD card in the SD socket the onboard eMMC should be available by the userguide

[ufedor]

Please provide U-Boot booting log and the mmc probing in this case.

Here is the U-Boot log and at the end of it the tryings with SD / eMMC

For Accessing e-MMC card, please follow below steps:

1. Remove SD Card.
2. Program rcw_1600_qspiboot_emmc.bin into alternate bank 4.
3. boot from QSPI bank 4.
4. On Uboot Prompt try mmc info command, It will display eMMC card details.

[gaborkocsis]

Well I tried these steps above , but the boot from altbank doesn't work at all. It boots from the Bank0 only.

I checked the rcw file it's in its place.

If I forced the boot from Bank 4 by DIP switch set, the ASLEEP LED stayed lit and the boot was failed.

To do this I performed the following steps:

=>tftp 82000000 rcw_1600_qspiboot_emmc.bin

=>sf probe 0:1

=>sf erase 0 +$filesize

=>sf write 82000000 0 $filesize;

=>cpld reset altbank
