How to disable the DDR3A

Charis Lee

Other Parts Discussed in Thread: TCI6638K2K

Dear support,

I hope I can receive help from you one more time.

I clone the U-Boot source tree from Arago git repository and download the kernel source code from the git repositories to the local Ubuntu.

What should I do to disable the DDR3A.

Thanks!

Hi,

Would you please let us know why do want to disable DDR3A?

Which processor device you use? Is it keystone - II?

Regards,
Shankari

Hi,
Thanks for your reply!
Our devive is TCI6638K2K,the DDR3A on our board is broken.Is it right No DDR3A can run only with DDR3B?
thanks

Hi Charis,

As of now, DDR3A is used to boot the u-boot.

If you want to use the DDR3B, you have to modify the u-boot source code.

Particularly have a look at modifying files, board_k2hk.c and ddr3_k2hk.c located at board/ti/ks2_evm

Regards,

Shankari

Hi,Shankari G :
According to your suggestion,I modify the void init_ddr3(void) in the ddr3_k2hk.c to
void init_ddr3(void){ char dimm_name[32]; u8 spd_buf[256]; int ddr_speed;
int ddr_size; struct ddr3_phy_config *phy_cfg = &phy_spd_cfg;
struct ddr3_emif_config *emif_cfg = &emif_spd_cfg;
/* First take care of DDR3B - simple case */
if (__raw_readl(K2HK_PLL_CNTRL_BASE + MAIN_PLL_CTRL_RSTYPE) & 0x1)
init_pll(&ddr3b_333);
init_ddrphy(K2HK_DDR3B_DDRPHYC, &ddr3phy_1333_2g);
init_ddremif(K2HK_DDR3B_EMIF_CTRL_BASE, &ddr3_1333_2g);
/* Apply the workaround for PG 1.0 and 1.1 Silicons */
if (cpu_revision() <= 1) ddr_reset_workaround();}
Now the u-boot and kernel can boot up ,but there is anthor problem at the log of kernel:
net eth1: netcp device eth1 opened dma dma1chan10: out of descriptors
dma dma1chan10: out of descriptorsSendind discover...Sendind discover...

Hi,Shankari G : I delete the Part of the DDR3A initialization!
I set the bootargs as "setenv bootargs 'console=ttyS0,115200n8 rootwait=1 earlyprintk rdinit=/sbin/init rw root=/dev/ram0 initrd=0x82000000,38M'" the size of tisdk-rootfs.cpio.gz is 38M.
when the kernel boot up,there is a error "initramfs unpacking failed: junk in compressed archive"
Expect your help,thanks！

Hi Shankari G: Thank you for your help!
After I disable the DDR3A,there is a message "The Host is not alive" under the u-boot ping PC.
Thanks!

HI, Charis,

what platform is this? and what the reason you want to disable DDR3A?

Rex

0 Charis Lee over 10 years ago in reply to Rex Chang

Intellectual 340 points

Hi,Rex, Thank you for your reply!
It is the TCI6638K2K, we modeled the xtcievmk2x to do our own board.Because we did not connect the IIC to the DIMM, I can not use the DDR3A.
Best Regards!

0 Rex Chang over 10 years ago in reply to Charis Lee

TI__Guru 50170 points

Hi, Charis,

It seems that you disabled the DDR3 successfully in u-boot and got the u-boot up and running. Your problem seems to be ping failed. Correct? You will need to debug the network issue why host is not alive.

Rex

0 Charis Lee over 10 years ago in reply to Rex Chang

Hi,Rex, Yes,you are right!On the arm CorePac,ping failed.But on the DSP CorePac with ping successful(with NDK code helloworld,the UDP routine).Please give me some advice to solve this issue.
Thank you!

Hi,
Able to brought up ethernet at u-boot stage ?
Did you change anything in kernel and dts fie regarding etherent or simply used pre-built kernel and dtb ?
What are the other changes you have in your custom board ?
Just DDR3B or any ethernet PHY etc.,

On the arm CorePac,ping failed.But on the DSP CorePac with ping successful(with NDK code helloworld,the UDP routine)

It seems, ethernet part is working good in your custom board.
Could you please tell us, how you are doing this ?
Running "DSP helloworld NDK" code on DSP core 0 by connecting JTAG with CCS and in parallel running Linux on ARM core ?

FYI: When you running NDK example on DSP core, it would initialize everything EMAC,PHY etc.,

0 Charis Lee over 10 years ago in reply to Titusrathinaraj Stalin

Hi, Thank you for your reply!1. NO,I ping failed at u-boot stage.
2. I clone the U-Boot source tree from Arago git repository and download the kernel source code from the git repositories then compile them and run at the xtcievmk2x board,the network is ok! Then I disable the DDR3A initatialization part and enable 10Git ethernet(sgmii_link_type is XGMII_LINK_MAC_MAC_FORCED),the network can not work.
3. We replace the MCU with FPGA.
4.I just running NDK helloword on DSP core 0 by CCS and after repower the board I running linux on ARM core 0.
Thanks!

Hi,
I set the DDR3A_REMAP_EN to 0 by pull GPIO16 to down,and change CONFIG_SYS_LPAE_SDRAM_BASE from 0x800000000 to 0x80000000.

0 Titusrathinaraj Stalin over 10 years ago in reply to Charis Lee

TI__Guru** 116100 points

Hi,

Thanks for the clarification.

I set the DDR3A_REMAP_EN to 0 by pull GPIO16 to down,and change CONFIG_SYS_LPAE_SDRAM_BASE from 0x800000000 to 0x80000000.

Understood, then only you able to access DDR3B at 0x80000000 as per the K2H memory map table.

So, I would like you to suggest to bring up the ethernet in u-boot first and later will focus in linux kernel.
Able to get the IP address automatically at u-boot through "dhcp" command ?

Are you trying to enable 10GbE ethernet or 1GbE ?

Have you taken the u-boot source from the following link ?

git clone git://git.ti.com/keystone-linux/u-boot.git u-boot-keystone

0 Charis Lee over 10 years ago in reply to Titusrathinaraj Stalin

Intellectual 340 points

Hi, Thank you for your quickly reply!
1. after I used "dhcp" command,"BOOTP broadcast "is display.
2.I want to enable both 10GbE and 1GbE.
3.Yes,I get the u-boot source from the link you give above!Thanks!

TI__Guru** 116100 points

Hi Charis
Did you solve your problem ?
If not, could you attach the modified files of u-boot to reproduce at our end with K2HK EVM board.

0 Charis Lee over 10 years ago in reply to Titusrathinaraj Stalin

Intellectual 340 points

Hi,

After I disable the DDR3A and set the REMAP_DDR3A_EN to 0,the logic address from 0x60000000 to 0x7FFFFFFF can not be used.whether this cause the exception?

The file attach is what I modified.

Thanks!
