ADSP-SC58x/2158x Simple Led- Example code for Boot Testing

Hi Harshit,

Thanks for this boot code. I also want to generate this ldr images for my sample application, and want to run the application as standalone. Can you please suggest me abt how to do it? Going through some of the documents, but not getting the clear picture.

Thanks in advance, waiting for your replay.

Hi Ksam,

I would request you to kindly go through the Application Note EE-384 which talks about loader stream generation in detail.

The link for the Application Note is given below:

Please let me know if you still face an issue in booting your application.

Thanks,

Harshit

Hi,

I used the code on ADSP-SC58x_EZ-KIT and it seemed to be flashed on the DSP and running.

The only thing I could not get it verify that it is working properly or not is that I could not get this development board LEDs (LED10 or 11 or 12) to blink using this code.

The board manual says these LEDs are for PE_13, PE_14 and PE_15 but I do not find a reference for these pins to modify the code you attached. I want to know how I can modify the code you attached in order to get these LEDs on the EVAL-SC589-EZLITE kit blinking?

Thanks

Hi Hassan,

These are configured in the PORT registers as shown below:

*pREG_PORTE_FER = 0;  // Using this as GPIO pin

*pREG_PORTE_DIR_SET  = 0xE0EE;  //Making PE13,14,15 as output pins

*pREG_PORTE_DATA_TGL  = 0x2002; // toggling these pins which will be reflected as LED blink.

In the attached zip folder, you can also see sample codes which you can run via emulator to see the LED toggling on single stepping these instructions in a code.

Thanks,

Harshit

Hi Harshit,

I've used your code on sc584-ezbrd LPC (to test if I can program SHARC code and see if it works).

I've flashed the SPI-NOR with Boot_Code/SPI_Master_Boot_Streams/SPIMASTER_Single_ARM_SHARC1.ldr 

After reset I do see two blinking LEDs...... LED10 and LED12.

This is good :-)

However, I would like to come back to my u-boot/Linux setup (I've followed ADI's CCES Linux manual).

I've reset the board with the push button, and before LEDs started blink I typed:

(gdb) target remote :3333

(gdb) load /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin/init-sc58x-ezkit-lpc.elf

(gdb) c
Continuing.

(gdb) c

Unfortunately, I do not see any output on the serial console (with u-boot prompt).  

I can only see the blinking LEDs when I reset the board.

Also OpenOCD do not show any errors:

target halted in Thumb state due to debug-request, current mode: Supervisor
cpsr: 0x400001f3 pc: 0x00001840, semihosting
MMU: disabled, D-Cache: disabled, I-Cache: disabled
semihosting is enabled

Could you help me with debricking the devel board?

Thanks in advance,

Łukasz

Hmm..... the problem has been solved....

It turned out that the example *-ldr file puts the Core0 (ARM-Cortex A5)
into thumb state.

How to debrick:

Start OpenOCD (the one from ADI's Linux CCES AddIN).

Open GDB:

target remote :3333

(issue this command when you release the reset push button) - so the SW from SPI-NOR won't start.

(gdb) set $cpsr = 0x1D3
(gdb) load /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin/init-sc58x-ezkit-lpc.elf
C

Ctrl+C

(gdb) load /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin/u-boot-sc58x-ezkit-lpc

C

And you should see the output from serial console :-)

After that one can restore the original u-boot/Linux.

Sorry for the noise :-)

Best regards,

Łukasz
