eMMC on LS1046ARDB

[boematic2007]

I'm looking at the Target Connection for the LS1046ARDB and the eMMC doesn't appear to be right.  The Target Initialization File has the eMMC list as:

fl.add_device({"alias": "mmc", "name": "MMCP1xxx_LSCH2", "address": 0x00000000, "ws_address": 0x80000000, "ws_size": 0x1FFFF, "geometry": "8x1", "controller": "eSDHC"})

But when I look at the schematic SPF-29142_C.pdf the eMMC is listed as MTFC4GACAJCN-1M.  Am I looking at that wrong?

And then try unzip the  "ls1046ardb_fip_uboot_emmc.7z", follow the screen snap fip.png.

Program both files to the eMMC.

Thanks

You could try unzip the "ls1046ardb_bl2_emmc.7z", follow the screen snap BL2.png .

If you could not download the firmware, please kindly let me know.

I upload "firmware_ls1046ardb_emmcboot", when I program the firmware into the LS1046ARDB, I could bring-up from the eMMC(without SD card insert)

You could find it in the

If you could not find it, please let me know.

Could your firmware work well when program it with the u-boot?

It's better your firmware is a golden version to try the program.

My firmware is too big to send it to you to try it.

Thanks

Here is more information.  I've been using the Target Configuration file from:

https://community.nxp.com/t5/CodeWarrior-for-QorIQ/LS1046ARDB-Bare-Metal-Flash-from-CodeWarrior/m-p/...

(ls1046ardb.py_2100&1600_pass.txt)

However, it has the flag USE_SAFE_RCW = False.  With this setting CodeWarrior returns an error trying to communicate with the eMMC.  I've tried this with the switches set to boot from QSPI and eMMC/SD with the same result.  

I changed the flag USE_SAFE_RCW to be True and it is now able to communicate with the eMMC.  At least, CodeWarrior will proceed through the Erase and Write parts of the Action.  However, with the switches set to boot from eMMC/SD I still see console output when powering on.

I have tried the eMMC program on the LS1046ARDB, it works well, so the eMMC algorithm work correctly.

Thanks for the reply and the screenshots. I have to set the USE_SAFE_RCW to true or otherwise every action fails that tries to communicate with the eMMC.  After that it does seem to communicate, performing the erase and programming.  However, after power cycling no console output.  Also, the output file from my build is named slightly different that yours.  Mine is named "firmware_ls1046ardb_uboot_emmcboot.img".
