add more SPORT to ucDemo for SC589 has run out of memory on L2 memory.

Hi,
You may need to adjust the L2 memory region in ARM and SHARC as well if your application cant fit in already allocated L2 cached and  un-cached memory. Please tryout the below steps,

1. In ARM project "system - Linker - ss4s.ld" file adjust the un-chaned memory 

 MEM_L2_UNCACHED : ORIGIN = 0x20084000, LENGTH = 76K 

2. Adjust the cached memory origin based on memory adjusted for "MEM_L2_UNCACHED " i.e.) 76K 

MEM_L2_CACHED : ORIGIN = 0x20097000, LENGTH = 32K 

3. If L2 cached not sufficient then adjust the required memory in MEM_L2_CORE2
 MEM_L2_CACHED : ORIGIN = 0x20097000, LENGTH = 64K 

MEM_L2_CORE2 (r) : ORIGIN = 0x200A7000, LENGTH = 32K

4. The "MMUConfig.c" in ARM project "system - MMU" should be adjusted for above L2 Memory adjustments as below,

  { 0x20084000u, 0x20096FFFu, ADI_MMU_RW_UNCACHED }, /* 76KB ARM uncached L2 */
#if defined(__ADSPSC582__)
{ 0x20088000u, 0x200A3FFFu, ADI_MMU_WB_CACHED }, /* 112KB ARM cached L2 */
{ 0x200A4000u, 0x200BFFFFu, ADI_MMU_RW_UNCACHED }, /* 104KB SHARC0, & 8KB boot code working area */
#else
{ 0x20097000u, 0x200A6FFFu, ADI_MMU_WB_CACHED }, /* 64KB ARM cached L2 */
{ 0x200A7000u, 0x200BFFFFu, ADI_MMU_RW_UNCACHED }, /* 88KB SHARC1, SHARC0, & 8KB boot code working area */
#endif 

5. The "app.ldf" in SHARC core projects "system - startup_ldf" should be adjusted, Since the SHARC L2 memory origin modified as below, 

   mem_L2B5B6_bw           { TYPE(BW RAM) START(0x200a7000) END(0x200affff) WIDTH(8) }

Please let us know if you are facing any issue or further clarifications.

Thanks.

Dear,

the following line must also be modified as follows:

   mem_L2B2toB4_bw         { TYPE(BW RAM) START(0x20088000) END(0x2009ffff) WIDTH(8) }
To 
   mem_L2B2toB4_bw         { TYPE(BW RAM) START(0x20088000) END(0x200a6fff) WIDTH(8) }

Is this correct?

Hi GEFO,

Yes it is good to modify all the memory blocks which are affected by L2 memory adjustments in ARM core.

Thanks.
