LS1021A-TWR boot from QSPI (and NVME system)

[Kensou]

Dear Sirs,

I have got a LS021A-TWR board, which I am using with SD Card for RCW, U-Boot and Linux Kernel.

My goal is to remove SD card and:

- Booting from QSPI

- Linux in QSPI or NVME

- Linux user space in NVME

Is there an easy manner to do this?

I saw a thread concerning QSPI boot, can I use this or have I to go with LSDK 2.0?

I refer to this one: https://community.nxp.com/t5/Layerscape/ask-for-a-whole-qspi-boot-image-for-ls1021a/m-p/608874

Thank you in advance

[Kensou]

I wrote the images/firmware_ls1021atwr_qspiboot.img in QSPI. Starting booting QSPI, u-boot stuck after the following messages:

After the messages, the system hang forever.

Switch configuration is:

SW2 00010000

SW3 01100001

Is this correct?

Here are the stepts to follow to install LSDK 2108 on QSPI of the ls1021atwr
1-Download the file called "firmware_ls1046afrwy_qspiboot.img"

If are you using Linux, you can use the next command line on the directory in which you want to save the file.
"wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_ls1021atwr_qspiboot.img"

2-Format one USB on "FAT32".

3-Put firmware_ls1021atwr_qspiboot.img file on a USB.

Note: For that procedure please boot your board from SD or NOR flash if you can't boot from QSPI

4-Under U-Boot send the next commands

usb start

fatload usb 0:1 $load_addr firmware_ls1021atwr_qspiboot.img

Program the firmware to QSPI NOR flash

sf probe 0:0

sf erase 0 +$filesize && sf write $load_addr 0 $filesize

after that you can boot from QSPI changing the configuration of the SW2 and SW3

For your application, I recommend using the NOR Flash because it's better documented, and we have an image with Linux available for that board.

This does not work.

U-boot exactly hangs at the same point:

Could anybody help me?

[Kensou]

I tried several ways but this is what I achieved:
Using this https://community.nxp.com/t5/Layerscape/ask-for-a-whole-qspi-boot-image-for-ls1021a/m-p/608874 guide I am able to generate QSPI uboot-with-spl.bin. Unfortunately the u-boot version of Qoriq SD 2.0 does not support NVME as it is older than NVME uboot support date.

I tried via LSDK 21.08, and I correctly generated these:

firmware/rcw/ls1021atwr/SSR_PNS_30/rcw_1200_qspiboot.bin.swapped
firmware/u-boot/ls1021atwr/uboot_ls1021atwr_qspi.bin
firmware/qe_ucode/iram_Type_A_LS1021a_r1.0.bin
images/flash_images.scr
linux/kernel/arm32/LS/ls1021a-twr.dtb
images/firmware_ls1021atwr_qspiboot.img

questions are:

- How and what have I to write in QSPI flash? I have to write directly the firmware_ls1021atwr_qspiboot.img in qspi? Is there a step-by-step procedure?

Moreover, is there a way for configuring the u-boot via LSDK 21.08 in order to enable the PCI and NVME?

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I tried via Codeaurora Yocto LSDK v20.04 dunfel: https://source.codeaurora.org/external/qoriq/qoriq-components/yocto-sdk/tree/readme?h=dunfell

Here what I found is:
- u-boot-ls1021atwr.bin-qspi

As previous I have to write the binary directly in qspi? Is there a step-by-step procedure?

Moreover, is there a way for configuring the u-boot via LSDK 21.08 in order to enable the PCI and NVME?

Thank you in advance.

The thread concerning QSPI boot that you shared in the description has the rights steps, so, you can follow the suggested on it.

Unfortunately the LS1021A-TWR doesn't have support for NVME media

best regards 

[Kensou]

Thank you for you reply.

Concerning the NVME, I am using NVME M2 PCIe adapter, so the LS1021A TWR is actually able to mount a formatted NVME using OpenIL and/or Real Time Edge.

So I am pretty sure that the LS1021-TWR supports NVME media with the adapter.

[Kensou]

I am actually trying OpenIL, OpenWRT and Real Time Edge with such adapters and NVME, they are actually working

[LFGP]

you have right, the ls1021TWR has support for the NVME ( u-boot drivers/nvme/nvme.c) via PCIe adapter with the LSDK 21.08 actually.

[Kensou]

So how can I generate QSPI boot firmware with LSDK 21.08?

[Kensou]

Nobody?
