processor sdk Uboot 2015.07 which is not booting through uart (uboot.uart) or thro ccs (uboot.bin).

Hi Sivanantham,

This thread has been split from below thread,

We will get back to with our response. Thank you for your patience.

Hi Sivanantham,

[Note: Please take the pre-built u-boot.bin as your first attempt.You can ignore the MCSDK version here and use processor SDK and follow the steps]

The following are the steps to get the u-boot prompt on K2H EVM through CCS which is the easiest method.

I have attached the necessary screenshots for your reference.

1. Flashing and booting u-boot.bin

======================

The u-boot.bin can be flashed into the EVM through CCS method.

1.1 HW Set up on K2HK EVM:

==================

   In EVMK2hk, rev 3.0 board, you will find two FTDI -USB connectors. The top one is for the emulator (CCS) and

   the bottom one is for opening two channels ( one for displaying the u-boot messages and another one is for BMC commands)

   Connect the USB cables between your host PC where in the CCS is installed and the K2HK EVM. One for Emulation and the other one for receiving the u-boot messages and the BMC commands.

   To flash the u-boot.bin,  EVM dip switches are to be set for no-boot mode

   SWITCH Pin1 Pin2 Pin3 Pin4

   SW1 Off Off Off On

1.2 CCS set up and u-boot flashing Steps to get u-boot prompt.

==================================================

   In CCS, navigate to view--> Target configuration--> create new target configuration file --> and open the file.

   Select the XDS2xx USB emulator as "connection" and "TCI6638K2K" as board/device, save and test connection.

   Now, launch the target configuration file and open -->view scripting console, you will get a console prompt with "js:>"

   You might have already installed the MCSDK at windows and you will find the js file at C:/ti/mcsdk_linux_3_00_03_15/host-tools/loadlin/loadlin-evm-uboot.js

   Connect the coretexA15_1 to the target.

   In the scripting console, use loadJSfile command to load the "loadlin-evm-kern.js" file. Before loading, openup the js file in CCS and modify the

   paths of u-boot, kernel like below

   PATH_LOADLIN = <path of release folder>/host-tools/loadlin

   var pathUboot = PATH_LOADLIN + "/u-boot-keystone-evm.bin";

   var pathSKern = PATH_LOADLIN + "/skern-keystone-evm.bin";

   loadJSFile C:\ti\mcsdk_linux_3_00_03_15\host-tools\loadlin\loadlin-evm-uboot.js

   ----> Observe a progress bar which will complete the loading of images given in the "loadlin-evm-uboot.js"

   ----> Hit the play button in CCS and in the tera term observe the output messages from "u-boot.bin" image ( flashed through CCS just now) and the u-boot prompt like below.

Hi,

      I am able to load u-boot.bin of  "K2_UBOOT_2013_01_15.07_01" tagged from ti git repository and it is working fine.

This uboot.bin is loaded thro CCS (loadjs file in script console) and uboot.uart. But latest PSDK uboot.bin image is not

coming up. I am not seeing any single print.

Now I think the topic is deviated because i have asked SRIO is not working in K2_UBOOT_2013_01_15.07_01" tagged uboot. When i was trying to read SRIO register thro uboot i am getting as 0x0.Eg: 0x0290b000 i should get vendor id. But i m getting 0x0

Please refer the below thread

Kindly suggest on this.

K2_UBOOT_2013_01_15.07_01" tagged

 Hi,

I am able to load u-boot.bin of  "K2_UBOOT_2013_01_15.07_01" tagged from ti git repository and it is working fine.

This uboot.bin is loaded thro

• CCS (loadjs file in script console)
• uboot.uart(thro uart by setting bootmode #4 in BMC)
• SPI boot (setting bootmode #2 in BMC)
• Nand boot(*.gph).(setting bootmode #0 in BMC

But latest PSDK uboot.bin image is not coming up in the above said method. I am not seeing any single print.

Now I think the topic is deviated because i have asked SRIO is not working in K2_UBOOT_2013_01_15.07_01" tagged uboot. When i was trying to read SRIO registers thro uboot (thro md command in uboot) i am getting all registers as 0x0.

Eg: md 0x0290b000 0x100 i should get vendor id. But i m getting all registers 0x0

Please refer the below thread

Hi,

             I am able to get the vendor ID as 0x30  at 0x0290b000 thro CCS SRIO loop back example project.

But not able to read the srio register thro u-boot. FYI, I am using keystone_rio.c file for enabling PSC,Block enable,global block enable.

My doubt is, any special step is required to read srio registers from ARM core? Since In CCS, DSPs alone is connected.Arm is in doconnected state.

Kindly help on this.
