mainlined u-boot with rockchip ddr blob

[ebin-dev]

@prahal There are two versions of the bootloader in the repository (edge and current).  

I just tried the current u-boot from the repository. It works but dmesg outputs seven of the following messages:

 

[    9.674633] rockchip-i2s ff8a0000.i2s: Could not register PCM

 

This note mentions that such error messages could mean that DMA and sound are missing in the linux kernel, could this be ignored ?

P.S.: Those messages are not thrown if the recommended bootloader (linux-u-boot-edge-helios64_22.02.1_arm64) is flashed to emmc.

Adding more clues from your issue:

Quote

current u-boot from the repository (linux-u-boot-helios64-current_24.5.0-trunk.608_arm64__2022.07-Se092-Pe990-H8c72-V65aa-Bf5f6-R448a)

 

this u-boot is I  guess, mainlain u-boot and ATF with rockchip DDR blob.

 

linux-u-boot-edge-helios64_22.02.1 is likely the rockchip ATF, miniloader and DDR blob.

 

 

Seems linux-u-boot-edge-helios64_22.02.1_arm64 is not available to download anymore? EIther way, this is a binary blob so could only be used to test feature parity.

 

apt policy linux-u-boot-helios64-edge
linux-u-boot-helios64-edge:
  Installé : 24.5.1
  Candidat : 24.5.1
 Table de version :
 *** 24.5.1 500
        500 http://apt.armbian.com bookworm/main arm64 Packages

     24.2.1 500
        500 http://apt.armbian.com bookworm/main arm64 Packages

 

the link you provided looks like a match for this issue.

 

 

I noted that

rockchip-i2s ff8a0000.i2s: Could not register PCM

is printed each time a USB device is plugged in (probably also when probed at boot).

 

also, it has been a long time I noticed:

juin 08 16:18:53 helios64 kernel: platform ff1e0000.spi: deferred probe pending: (reason unknown)

juin 08 16:18:53 helios64 kernel: platform ff1d0000.spi: deferred probe pending: (reason unknown)

at the end of the kernel boot log. (ie kernel giving up trying to load the drivers for these).

Seems related too.

Since linux-u-boot-edge-helios64_22.02.1_arm64 does'nt seem to be downloadable anymore from Armbian servers, I added a download link to it from my dropbox account.
