Boot failed after programming flash with large size binary although the size is within serial flash memory

Category: Software
Product Number: ADSP-SC594
Software Version: CCES 2.10.1


I have two problems about programming flash memory.

The two symptoms are related with the size of binary file to be programmed.

For example,

case 1) 336 KB binary: no problem! ok

case 2) 8.2 MB binary: small symptom

In console screen of flash programming batch program, writing process finished well, but verifying process halts.

At that time, I terminate the process and repower board, then it boots ok.

case 3) 21.7 MB binary: critical problem

The verifying process halts as above.

and after repowering, boot fails as SYS_FAULT led on.

The specification of our system is as follows:


CCES: v2.10.1

emulator: ICE-1000 

Flash memory: IS25LP512M (capacity 512Mb = 64MB)

Driver file: is25lp512m_dpia_SC594_Core1.dxe

The content of batch file:

"C:\Analog Devices\CrossCore Embedded Studio 2.10.1\cldp.exe" -proc ADSP-SC594 -core 1 -emu ICE-1000 -driver "is25lp512m_dpia_SC594_Core1.dxe" -cmd prog -erase affected -format bin -file "VC_CM_Core0.ldr" -cmd compare -format bin -file "VC_CM_Core0.ldr"


==The end==


Is there anyone who experiences this problem or can help me?

Thank you in advance.

  • Hi Divya.P

    In fact, initially I used 'intel hex' ldr format which is default setting.

    With the setting, it had the same problem, and I have been trying inspection using 'bin' ldr format because bin ldr is actual size which is programmed on flash memory. (intel hax is ascii format and its ldr has twice or more times larger size as fas as I know)

  • Hi Divya.P

    You told the issue had got simulated in SC594 SOM board. 

    How was the result? 

    Do you have such symptom at your side?

  • Hi Divya.P

    Today our staff found there is an option to expand address mode of is25lp512m flash to use complete memory range.

    C:\Analog Devices\EV-SC59x_EZ-KIT-Rel2.0.0\EV-SC59x_EZ-KIT\Examples\Device_Programmer\Legacy_SPI_ISSI_Flash\main.h


    At first, we expected this would solve the problem, but disappointedly the problem is still with newly compiled is25lp512m_dpia_SC594_Core1.dxe binary.

    probable causes:

    > There is some error on ENABLE_EXTENDED_ADDRESSING_MODE related code. -> error in flash write?

    > There is something error or range limit in booting process which reads from flash to RAM -> error in flash read?

    > or our fault on what?

  • Hi Johnny Jeong,

    We are actively working with our experts in this case, will get back to you as soon as possible.


  • Hi Johnny Jeong,

    Apologies for the delay in response.

    It is recommended to change byte addressing from 3 byte to 4 byte in flash to be used to access the memory array beyond 128Mb.

    Please follow the instructions below to change the addressing mode:

    1. Include and call the attached function in Init code and build it. Use this modified initcode while creating loader file.

    2. Enable the below macro in device programmer code.

    #define ENABLE_EXTENDED_ADDRESSING_MODE 1 /* Enable extended mode of access to the complete Flash address space */

    Use modified 25lp512m_dpia_SC594_Core1.dxe in CLDP .

    By following the above steps, we can boot 16.5MB LDR in binary format, in our SC594 Ez-kit.

    Please try this and let us know the results.


  • Hi Divya.P

    I have just checked what you informed.

    It works! 

    This issue may have bothered you as well as me.

    You did good job!

    Thank you a lot.

    Best regards,
