Custom u-boot with SHARC firmware for SC589

Hi,

I've made many tests but i'm still stuck with a custom u-boot problem.

 

I create a custom u-boot (make menuconfig / make) in ~/sc58x/uboot folder

This create me a new u-boot and it works fine, I can load it from previous u-boot, store it to flash, and so on...

 

But

When I try to create a custom u-boot with SHARC firmware inside I experience a complete u-boot crash.

Here's what I've done:

 

   1. Create a loader with elfloader (under windows)

elfloader.exe -proc ADSP-SC589 -si-revision any -b spimaster -f binary -width 8 -bcode 1 -init init -core0=u-boot -core1=MCAPI_Msg_SC589_SHARC_Core1.dxe -NoFinalTag=u-boot -NoFinalTag=MCAPI_Msg_SC589_SHARC_Core1.dxe -o u-boot-mcapi.ldr

 

 

   2. Boot and stops boot of my SC589 by pressing a key

In u-boot, I set some parameters

set serverir myip

set ubootfile u-boot-mcapi.ldr

 

   3. Try an update

run update

 

The u-boot loads the code without any error.

 

But:

If I try to save current u-boot parameters (with command save)

Or if I reboot the board

 

The board crash (with no serial log).

 

The only way is to restore a default-uboot with

cldp -proc ADSP-SC589 -core 1 -emu 1000 -driver "C:\Analog Devices\ADSP-SC5xx_EZ-KIT_Lite-Rel2.0.1\ADSP-SC5xx_EZ-KIT\Examples\Device_Programmer\sc589\sharc\sc589_w25q128fv_dpia_Core1\sc589_w25q128fv_dpia_Core1.dxe" -cmd prog -erase affected -format bin -file u-boot-sc58x-ezkit-hpc.ldr

 

Do you have any advice ?

Is it a flash address error or integrity loss ?

 

Final goal is to have an u-boot containing :

   * original u-boot for ARM

   * SHARC core 1 firmware

   * SHARC core 2 firmware

 

 

I saw many post about embeddingboth SHARC firmware into u-boot, but don't find a simple procedure for this.

 

Any ideas will be welcome.

 

Regards
