From these two lines,

Spi_ChipId = ffffff
SpiBootInit:ffffffff

I think the SPI Flash is not recognized.

#3

Thank you for your response @Stephen.Then what I do and what is the procedure.Please help me.

#4

Did you forget to remove the line between PIN#23 and PIN#25 before using tool rkdeveloptool to flash the images to the SPI Flash?

#5

Hello @Stephen.,
once I tried but mode was changed maskrom mode to loader mode(if I am remove connection between 23 pin and 25 pin).So,please help I have two query.

1.I am trying to load image in which mode ?
2.Which I follow this was the process to load images in SPI.
->sudo ./rkdeveloptool wd 0 path/image
-> and I am trying to load(rockpi4-debian-stretch-desktop-arm64-20190730_2022-gpt.img) this image.Is this correct image for SPI ?

If you have how to boot ROCKPI 4B board through SPI step by step then please share with me.

Question one.
When you finish the Step 2, Boot the board to maskrom mode, of https://wiki.radxa.com/Rockpi4/dev/spi-install, ROCK Pi 4 board is in maskrom mode.

When command, sudo rkdeveloptool db /path/to/rk3399_loader_spinor_v1.15.114.bin, is done, the board is in loader mode.

Then you can use command, sudo rkdeveloptool wl 0 /path/to/uboot-trust-spi-20190816_1128.img, to write image to SPI Flash.

Question two.
Where are SPI Flash images? they are here, https://dl.radxa.com/rockpi/images/loader/spi/. You can select https://dl.radxa.com/rockpi/images/loader/spi/rockpi4b-uboot-trust-spi_2017.09-2681-geb41d9a6ce_20191104.img for ROCK Pi 4B.

rockpi4-debian-stretch-desktop-arm64-20190730_2022-gpt.img is not a SPI Flash image. It is a full system that can be installed into eMMC module, TF card, NVME M.2 SSD.

Where is the guide for SPI and NVME booting? you can find it here, https://wiki.radxa.com/Rockpi4/Linux_system_runs_on_M.2_NVME_SSD.
