LS1021A-IOT QSPI boot

[Kensou]

hello everybody,
I need urgently a way for generating LS1021A-IOT QSPI boot image.

OpenIL, OpenWRT en Real-Time-Egde are only able to generate SD Card images.

LS1021A-IOT SDK 0.4 seems to be not available anywhere.

I need urgently an SDK or similar for generating LS1021A-IOT QSPI, could anybody help me about?

Thank you in advance.

I tried to replace u-boot-ls1021aiot.bin with one generated bonus my own.

I downloaded u-boot sources, used ls1021aiot_qspi_defconfig and then generated u-boot binary.

After this, I byteswapped the u-boot bin using your tcl byteswap script and flashed the so generated u-boot-byteswapped.bin in 0x10000 instead of u-boot-ls1021aiot.bin. In u-boot TEXT_BASE is correctly set as 0x40010000.

Unfortunately this not works. I see nothing at console log. Reset led goes off so I suppose RCW load went good with reset cycle completed.

What could it be the problem? I used the most recent uboot version (2023.4-rc3) so could it be a compatibility issue?

I tried to compile by myself ls1021aiot u-boot, by downloading u-boot sources, using ls1021aiot_qspi_defconfig, byteswapped u-boot.bin as per your tcl script, and then using the so generated u-boot-swapped.bin binary instead of your one.

TEXT_BASE is regularly set at 0x40010000

This seems not to work, I do not see anything at console log. Reset led is off so rcw was correctly loaded. I used the latest u-boot, 2023.4 version. Could it be a compatibility issue?

1. Files
u-boot-ls1021aiot.bin
rcw/ls1021aiot/RSR_PPS_70/rcw_1000_qspiboot_swap.bin

2. Map
rcw: 0x0 - 0x100
u-boot: 0x10000 - 0x90000
u-boot env: 0x100000 - 0x120000

3. Dip switch settings
For QSPI boot, SW2.1 = ON

3.1 rcw/ls1021aiot/RSR_PPS_70/rcw_1000_qspiboot_swap.bin
Dip Switch: SW2.5 = OFF
Brief: ETH0 disabled
SATA enabled

4. Assume qspi is empty, boot from SD card first, the run the following
commands to flash the images to QSPI.

4.1 rcw/ls1021aiot/RSR_PPS_70/rcw_1000_qspiboot_swap.bin and u-boot
=> sf probe
=> sf erase 0x0 0x100000
=> tftp 0x82000000 rcw/ls1021aiot/RSR_PPS_70/rcw_1000_qspiboot_swap.bin
=> sf write 0x82000000 0x0 0x100
=> tftp 0x82000000 u-boot-ls1021aiot.bin
=> sf write 0x82000000 0x10000 0x80000

How to generate rcw_1000_qspiboot_swap.bin and u-boot-ls1021aiot.bin? I need a procedure or a SDK.

Sorry, we do not have the components of that software because that board was made for an NXP partner, that information only can be provided by your distributor on a USB inside the package on the board, please contact your distributor.

We only have the first image for that board and we don't have the latest for that board.
