TFTP MCSDK video in big Endean mode

Hi Vinit,

Can you please summarize the changes you have done to compile MCSDK Video DSP build for Big Endian?

As for the switch setting, SW3 has the endian mode. Please refer to the following link for the details:  http://processors.wiki.ti.com/index.php/TMDXEVM6678L_EVM_Hardware_Setup#Hardware_Setup_Steps.

Thanks,

Hongmei

Hi Vinit, which demo are you trying?

thank you,

Paula

Hi Hongmei,

Following changes were made to build on big endian:

1)XDC,PDK and nwl lib taken for build is big endian also FC used is framework_components_3_23_02_16.
2)bootsh link and boot map are build for big endian elf.
3)Codec lib is build in big endian.
4)tftp,neu,pkutil and types module lib are build in big endian.
5)Build properties are changed to big endian.

Hi Paula,

I am trying with H264HP encoder.

Hi Hongmei,

Any suggestion?

Hi Vinit,

Please try the following to switch IBL from LE to BE and check if you can get BOOTP packet from DSP when using ROM Ethernet boot mode.

Steps to flash IBL can be found from http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide#IBL.

Please note that the steps here are written for little endian. Because of this, we need to use big endian .bin and .out file from [bios_mcsdk install dir]\tools\boot_loader\ibl\src\make\bin folder. The eeprom writer .out file under [bios_mcsdk install dir]\tools\writer\eeprom\evmc6678l\bin is in LE mode, and therefore needs to be rebuilt for BE. Instructions for rebuilding eeprom writer can be found from [bios_mcsdk install dir]\tools\writer\eeprom\docs\README under "Steps to re-build eepromwriter".

When doing the flash, please ensure dip switch 3 is set for Big Endian (http://processors.wiki.ti.com/index.php/TMDXEVM6678L_EVM_Hardware_Setup#Hardware_Setup_Steps)

After the IBL is switched to BE, please set the switch settings to ROM Ethernet Boot mode (with Big Endian). http://processors.wiki.ti.com/index.php/TMDXEVM6678L_EVM_Hardware_Setup#Boot_Mode_Dip_Switch_Settings. Then, power cycle DSP and check if there is BOOTP packet coming from DSP.

Thanks,

Hongmei

Hi Hongmei,

I have switched IBL to BE. Flashing was successful.Still getting same error at QMSS_Init module.

Hi Vinit,

After switching IBL to BE, did you get BOOTP packet from DSP by just powering cycle the EVM (ROM Ethernet Boot mode)?

Thanks,

Hongmei

Hi Hongmei,

I am not getting BOOTP packet from DSP after flashing Big Endian IBL .(ROM Ethernet BOOT mode SW3 Pin1 -Big Endian).

Please note:With Little Endian IBL we got BOOTP by just powering cycle the EVM.

Vinit

Hi Hongmei,

These are the steps followed while flushing in Big Endian:

1)eepromwriter_evm6678l.out located at ..\tools\writer\eeprom\evmc6678l\bin built in big endian mode.
2)Copied  i2crom_0x51_c6678_be.bin from ..\tools\boot_loader\ibl\src\make\bin to ..\tools\writer\eeprom\evmc667#l\bin. Copied file renamed to app.bin.
3)eepromwriter_input.txt in ..\tools\writer\eeprom\evmc6678l\bin. file_name  setequal to app.bin and bus_addr equal to 0x51. Madesure start_addr and swap_data are set to 0. 
4)EVM switched to No boot mode.
5)Connect and gel file load.
6)eepromwriter_evm6678l.out  loaded on core 0.
7)Memory load of app.bin at  0x0C000000 (size 32-bits).
8)"EEPROM programming completed successfully" displayed at console.
9)i2cparam_0x51_c6678_be_0x500.out located in the ..\tools\boot_loader\ibl\src\make\bin loaded.
10)i2cConfig.gel GEL file, located in the ..\tools\boot_loader\ibl\src\make\bin loaded.
11)Run program followed by "EVM c6678 IBL" -> setConfig_c6678_main.
12)"I2c table write complete" displayed at console.

Hi Vinit,

Which version of BIOS MCSDK did you use for the IBL flash?

Thanks,

Hongmei

Hi Hongmei,

I have user BIOS MCSDK 02_01_02_05 for IBL flashing.

Vinit

Hi Hongmei,

Can we use same gel file for Big endian?

Regards

Vinit

Hello Vinit,

Yes, you can use the same GEL file. We are going to investigate this and I will give you feedback asap.

David

Hi David,

I did get BOOTP packets in BE mode.

Thanks 

Vinit

Hi Hongmei/David,

I did get BOOTP packets in BE,but my MCSDK still returns fail at QMSS_Init function.

Regards

Vinit

Hi Vinit,

Can you please provide all the files you have modified from MCSDK Video in order to use big endian?

Thanks,

Hongmei
