ebin-dev Posted June 11 Share Posted June 11 (edited) @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.

prahal Posted June 11 Share Posted June 11 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 100 /var/lib/dpkg/status 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 ff200000.spi: deferred probe pending: (reason unknown) juin 08 16:18:53 helios64 kernel: platform ff8a0000.i2s: deferred probe pending: (reason unknown) juin 08 16:18:53 helios64 kernel: amba ff6d0000.dma-controller: deferred probe pending: (reason unknown) juin 08 16:18:53 helios64 kernel: amba ff6e0000.dma-controller: 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. 0 Quote Link to comment Share on other sites More sharing options...

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. 0 Quote Link to comment Share on other sites More sharing options...
