Hey guys,

bunch of thanks for your great work. 

Was wondering what's up with the latest buster images (20.05.2-5.4.43) for the 1Gig A versions. 

Worked great up to 20.02.11-5.4.32. 

 

The boot gets up to changing  the freq, then nothing :

 

 

> change freq to 416MHz 0,1
   Channel 0: LPDDR4,416MHz
   Bus Width=32 Col=10 Bank=8 Row=14 CS=1 Die Bus-Width=16 Size=512MB
   Channel 1: LPDDR4,416MHz
   Bus Width=32 Col=10 Bank=8 Row=14 CS=1 Die Bus-Width=16 Size=512MB
   256B stride
   channel 0
   CS = 0
   MR0=0x19
   MR4=0x3
   MR5=0x6
   MR8=0x0
   MR12=0x72
   MR14=0x72
   MR18=0x0 
   MR19=0x0
   MR24=0x8
   MR25=0xFF
   channel 1
   CS = 0
   MR0=0x19
   MR4=0x3
   MR5=0x6
   MR8=0x0
   MR12=0x72
   MR14=0x72
   MR18=0x0
   MR19=0x0
   MR24=0x8
   MR25=0xFF
   channel 0 training pass!

   channel 0 training pass!
   channel 1 training pass!
   channel 0, cs 0, advanced training done

 

  

Can you try to increase the boot verbosity?

https://docs.armbian.com/User-Guide_Fine-Tuning/#how-to-toggle-verbose-boot

Unfortunately this is the output with Verbose=7.

On the download pages https://www.armbian.com/rock-pi-4/ its written "1Gb model currently not supported" which means its known that it doesn't work ... probably recent u-boot does not support this memory configuration. Device sits on my desk because of this reason, but time is missing component ... I could allocate it only to write that note and open a Jira https://armbian.atlassian.net/browse/AR-282

 

Understood, is cool Igor, I sow the message, I was just curious to see  what is the issue.  

Btw is the RAM configuration done only here:

  "/arch/arm/mach-rockchip/sdram_common.c"  ?

From your log it seems that the issue is way before u-boot - in DDR blob from Rockchip.

Can you check if booting this image is successful for you?

 

It is built using Armbian master with DDR binary downgraded from v1.24 to v1.20 - the version used by Radxa to build their images.

Both versions work on my 4GB unit but I guess v1.20 was thoroughly tested on 1GB unit by Radxa ;-)

@piter75 Cool thanks I will test it! 

@piter75 Indeed you are right. Thanks, it neatly works.  The log here  . 

Would you mind to share how you patched the build  process, i'll try to build a stable "a"  version  too.

I am glad it worked!

The fix is pretty straightforward ;-)

Awesome! hope we get the fix it in 20.05.

Wondering what has Rockchip "fixed" with the v1.24 tho. Is there a release doc somewhere to read for this version?
