PROCESSOR-SDK-AM335X: ID EEPROM issue

Hi Yorden,

I discover to modifying the path caused by  I do n`t want read Board ID in my  am335 platform.

So , I  modified in the path: ~/ ti-processor-sdk-linux-am335x-evm-pure / board-support / u-boot-2017.01 + gitAUTOINC + c68ed086bd-

gc68ed086bd / board / ti / am335x $ /     at   the  Board .c and Board.h   2 files.

My way is to specify directly return A335X_SK but why I booted through the putty read message to see is the A335_ICE module

Please see the below picture :

I Provide the Board.c and Board.h  2 file in the attachment  

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/BOARD.7z

Could you give some suggestions for me?    Thank you.

Hi  Yordan,

I tried to modify the am335x_evm.h　file in your way, but after compiling, I produced the result of the screenshot below.

Is this the program that is not correctly declared?

Hi  Yordan,

I follow the before the rule and your remind,  But retry the boot on the system will hang up and putty show "Starting Kernel ....." (Please the screenshot below)  

I modified the following  4 files : 

1. u-boot /board/ti/am335x/board.c   ========>  remark   void do_board_detect(void)

2.  u-boot/include/configs/am335x_evm.h   ==============>  modify "fdtfile=am335x-evmsk.dtb\0" \ 

========================remove==========================================

"findfdt="\ 
"if test $board_name = A335BONE; then " \
"setenv fdtfile am335x-bone.dtb; fi; " \
"if test $board_name = A335BNLT; then " \
"setenv fdtfile am335x-boneblack.dtb; fi; " \
"if test $board_name = BBG1; then " \
"setenv fdtfile am335x-bonegreen.dtb; fi; " \
"if test $board_name = A33515BB; then " \
"setenv fdtfile am335x-evm.dtb; fi; " \
"if test $board_name = A335X_SK; then " \
"setenv fdtfile am335x-evmsk.dtb; fi; " \
"if test $board_name = A335_ICE; then " \
"setenv fdtfile am335x-icev2.dtb; fi; " \
"if test $fdtfile = undefined; then " \
"echo WARNING: Could not determine device tree to use; fi; \0" \

========================remove==============================

3. u-boot/arch/arm/mach-omap2/am33xx/board.c   

============remark===================== 

//#ifdef CONFIG_TI_I2C_BOARD_DETECT
//do_board_detect();
//#endif

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

4. u-boot/arch/arm/mach-omap2/am33xx/Kconfig

============remark===================== 

//select TI_I2C_BOARD_DETECT 

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

In addition, I would like to ask if this path u-boot /board/ti/am335x/     

The board.h file needs to be remark with TI other modules, leaving only am335x-SK return 1 to set it ?

static inline int board_is_bone(void)
{
//eturn board_ti_is("A335BONE");
//return 0;
}

static inline int board_is_bone_lt(void)
{
//return board_ti_is("A335BNLT");
//eturn 0;
}

static inline int board_is_bbg1(void)
{
//return board_is_bone_lt() && !strncmp(board_ti_get_rev(), "BBG1", 4);
//eturn 0;
}

static inline int board_is_beaglebonex(void)
{
//return board_is_bone() || board_is_bone_lt() || board_is_bbg1();
//return 0;
}

static inline int board_is_evm_sk(void)
{
return board_ti_is("A335X_SK");
return 1;
}

static inline int board_is_idk(void)
{
//return !strncmp(board_ti_get_config(), "SKU#02", 6);
//return 0;
}

static inline int board_is_gp_evm(void)
{
//return board_ti_is("A33515BB");
//return 0;
}

static inline int board_is_evm_15_or_later(void)
{
//return (board_is_gp_evm() &&
//strncmp("1.5", board_ti_get_rev(), 3) <= 0);
//return 0;
}

static inline int board_is_icev2(void)
{
//return board_ti_is("A335_ICE") && !strncmp("2", board_ti_get_rev(), 1);
//return 0;
}
