CCS/AM3358: RTOS bootloader

Frank

Thanks for your reply. I have tried like this:

1. Using CCS load nand_flash_writer_AM335x.out in "C:\ti\pdk_am335x_1_0_16\packages\ti\starterware\tools\flash_writer\".

2. Select SBL file ,the path is "C:\ti\pdk_am335x_1_0_16\packages\ti\starterware\binary\bootloader\bin\am335x-evm\gcc\bootloader_boot_nand_a8host_debug_ti.bin"

3.Select BCH 8bit. Then wait until nandwriter give "NAND flashing successful" tips 

4. tiimage my application . 

tiimage.exe 0x80000000 NONE AM335x_arm.bin AM335x_arm_ti.bin

5. Reload nand_flash_writer_AM335x.out, and select the file AM335x_arm_ti.bin.

6.  Flash offset I enter into 0x80000. And scheme type also is BCH 8 bit.

7. Waiting console tip finished.

But the result is my application isn't work. My application is a network program , I can ping from computer to board when I use emulator mode. However I disconnect CCS connection , power on , It doesn't get my expect.

Choose your operation
Enter 1 ---> To Flash an Image
Enter 2 ---> To ERASE the whole NAND
Enter 3 ---> To EXIT
1
Enter image file path
C:\ti\pdk_am335x_1_0_16\packages\ti\starterware\binary\bootloader\bin\am335x-evm\gcc\bootloader_boot_nand_a8host_debug_ti.bin
Enter offset to be flashed (in hex):
0
Choose the ECC scheme from given options :
Enter 1 ---> BCH 8 bit
Enter 2 ---> HAM
Enter 3 ---> T0 EXIT
Please enter ECC scheme type :
1
Starting AM335X NAND writer

The NAND Flash is ONFI compatible

Hi Gao,

Are you using a TI hardware platform? Note the only TI platform which supports NAND is the AM335x GP EVM. Please see http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_03_00_106/rtos/index_Foundational_Components.html#boot-modes-supported.

The following documentation contains useful tips on bootloader debugging: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_03_00_106/rtos/index_Foundational_Components.html#bootloader-debugging

Hi Frank.

I am using custom board. I know maybe I need make some changes in SBL. So, I recreate a project , and copy sbl file to my project. 

But the project Building happen a error.  The project is using CCS empty project , CCS add two files in the project: Am335x.lds and startup_ARMCA8.S.

I must modify project attribute : Use floating point hardware(-mfloat -abi) to hard, otherwise threre are so many error about lib files. such as:

....

So I add -hard to the attrbute. But emit the following 3 point symbol undefined , can you give me some suggestion?

Hi Frank.

Thanks. You are  help me alot, very thanks. My custom board has boot, everythings are ok.

Hi Gao,

I'm glad to hear boot is working on your board! I'll close this e2e thread.

Regards,
Frank
