PINE64 Rock64 - How to get SPI driver working

Hello,
I just compiled U-Boot v2020.04 for a PINE64 Rock media board. It compiles fine without errors, but when I try to probe the on board flash I get an error:
=> sf probe Invalid bus 0 (err=-19) Failed to initialize SPI flash at 0:0 (error -19) =>
SPI is activated in the Device-Tree blob. I also added support to the Rockchip SPI driver (added IDS strings for this SoC).
In the device config I added the following:
CONFIG_SPI=y CONFIG_ROCKCHIP_SPI=y CONFIG_SPI_FLASH=y
But the driver still doesn't work. Output of DM (shortened):
=> dm tree [...] spi 0 [ ] rockchip_spi |-- spi@ff190000
spi_flash 0 [ ] spi_flash_std | `-- spiflash@0 [...]
What is missing? Is there a way to load driver?
Any kind of help is highly appreciated.

Hello,
I want to add a helper function to uboot i.e uboot# help will show a list of commands. I want to add 1 for my own private command. which file contains the list of cmd that will be displayed and the indirection? thanks -kamal

Jagan may some idea here.
I would suggest you to add some log in the spi/flash driver for bind, probe and etc
to check what's wrong.
Thanks,

Hi Kever,
I think you answered the wrong person. :)
Okay, thanks for the suggestions.
I will check the sources. There was also a missing alias in the Device-Tree source. I have added the specific alias for the SPI bus. Now I'm getting the error code -2.
I'm new with U-Boot and the source code itself, but I think the problem occurs still in the device tree file for the specific board.
Cheers,
Johannes K.

Make sure you enable the driver for the actual flash chip too, some of the popular ones are: CONFIG_SPI_FLASH_WINBOND=y CONFIG_SPI_FLASH_MACRONIX=y CONFIG_SPI_FLASH_SPANSION=y CONFIG_SPI_FLASH_GIGADEVICE=y

I have enabled 'CONFIG_SPI_FLASH_GIGADEVICE'. But still getting the same error code (-2). On board is the GD25Q127C from Gigadevice.
The device ID for the operation code 0x9F according to the datasheet should be 0xC84018. I also found this device ID in the SPI-NOR IDS file.

I finally resolved the issue:
=> sf probe SF: Detected gd25q128 with page size 256 Bytes, erase size 4 KiB, total 16 MiB =>
The flash device will be correctly detected. The problem was missing support in the clock driver of the SoC.
Should I release a patch for it?

Add U-Boot SPI support for the RK3328

It's a initial SPI support. Not sure if "rk3399_spi_params" is also needed. Probing of the SPI flash devices works. Tested with the PINE64 Rock64 board.

Hi Johannes,
The changes look good to me, but you need to split the patch into 3 patches:
- rk3328 clock driver;

- rk3328-u-boot.dtsi
BTW: the patch no need reply-to previous mail, you can make a new thread.
