ICE Board AM3359 Flash the Application :

Bindu Ganesh

Other Parts Discussed in Thread: AM3359, SYSBIOS

Hi ,

We have ICE Board AM3359 with us

1) We followed the procedure to " Flashing Binaries to SPI Flash on ICE Using CCS" mentioned in below link and were successully able to flash it

http://processors.wiki.ti.com/index.php/AM335x_SYSBIOS_Industrial_SDK_Getting_Started_Guide

2) When we tried to flash the application code provided in sdk with the same procedure provided in above link we were successfully able to Flash it ,

Below is the example found in sdk

C:\ti\am335x_sysbios_ind_sdk_prebuilt_01_00_00_04\i2c_led\SPI\i2c_led_SPI.bin

3) But when we tried to flash the application code "C:\ti\am335x_sysbios_ind_sdk_1.0.0.4\sdk\protocols\ethercat_slave\ecat_appl\Debug\ecat_appl.bin"

Note :- We have the ethercat stack with us

we found the below message in CCS, but it was not flashed

[cortexA8] Erasing flash at byte offset : 131072, byte length : 98304

[cortexA8] SF : Windbond : successfully erased 98304 bytes @ 0x38000

[cortexA8] writing flash at page offset : 512, number of pages : 371

[cortexA8] Verifying...

[cortexA8] Success

Can any one please help me out, what is the exact procedure to flash our application code in ICE Board.

Hi Bindu,

Looks like you have flashed the binary successfully. but a binary( ecat_appl.bin) without any header.

You need to flash ecat_appl_SPI.bin tp SPI flash.

Shahid,

we build the ecat_appl in release mode, but we could find only ecat_appl.bin,

can you please mention where we can find this ecat_appl_SPI.bin , else what is the procedure to generate ecat_appl_SPI.bin

Looks like you have flashed the binary successfully. but a binary( ecat_appl.bin) without any header, which header need to be included?

Thanks,

Bindu

when Sitara tries to boot from spi0, romcode reads the first bytes of the flash. If 0xFfffffff is returned, romcode passes to next peripheral defined sysboot configuration. From a generated binary file, you have to add a 8 bytes header and then convert each packet of 4 bytes in MSB format.

so, Header struct is as following:

long (msb format) : size of binary file + sizeof struct header(i.e 8 bytes)

long (msb format): @ where bootloader or application is loaded inside sitara

To convert your binary (in little endian) read 4 bytes and shift them in msb format as following: (repeat until eof)

example: 0x12 0x34 0x56 0x78 => 0x78563412

it is easy to write this converter in C.

why you have to swap bytes?

Romcode configures spi0 in 32 bits "word" for transfering data to accelerate download. So automatically, 4 bytes are copied (swapped) in right order.

Hi,

Is there any way to convert the application binary to application_SPI binary using command prompt?

Is there any tool available in SDK for this convertion, where we can flash the application code.

Bindu,

ISDK already has tool to generate binary with header and it is used in all example application in ISDK. Please see project porperties->Build->steps->Post_build steps of any isdk example.

Also, this is described in user guide - http://processors.wiki.ti.com/index.php/AM335x_SYSBIOS_Industrial_SDK_01.00.00.08_User_Guide#Generating_Executable_Binary_-_Post_Build_Script

BTW, which sdk version are you using ?

Shahid,

Thanks for the responce.

We are using " am335x_sysbios_ind_sdk_1.0.0.4 " , when we started sdk_1.0.0.4, was the latest release

Were you able to generate _SPI .bin file ?

If not, paste the below line in post-build steps and rebuild the app. You should see the bin file.

"${IA_SDK_HOME}/tools/post_build/post_build.bat" "${CCS_INSTALL_ROOT}" "${CG_TOOL_ROOT}" "${PWD}" "${ProjName}" "${IA_SDK_HOME}/starterware/tools/ti_image" "1" "0" "0x80000000" "0x80000000"

Where IA_SDK_HOME is you sdk path.

Shahid,

Thanks for the response,

Can you guide me where can i find the " post-build steps ",

Tried to find them in Build configuration of ccs , but could not find. is there any other way to generate SPI.bin "Command line pattern" from ccs?

Thanks,

Bindu

Shahid,

Thanks for the responce.

We were able to generate "ecat_appl_SPI"
