Hi Socrates,

I have forwarded your question to VisionSDK expert, he will respond here.

You can also check the document in this link for description of memory layout in VisionSDK to see if it can give you some direction:

Which is the vision SDK version you use?

what is the plaform slected, does it TDA2x, TDA3x etc.?

What is A15 side OS, Bios or Linux?

Hi Shiju,

Platform : TDA2x
Package: VSDK 2.10
A15 side OS: BIOS

The pdf you have shared is for VSDK2.12. In fact we do not have any plan of migrating to VSDK 2.12.

Please help

Thanks
Socrates

Socrates

can you please provide more details on which memory section you have increased and how much?

Hi Shiju,

PFA mem_segment_definition_512mb_bios.xs for your reference.

We have increased DSP2_DATA_SIZE as 72*MB;

Thanks

Hi Socrates,

Just to confirm when you are building your code do set ECC_FFI_INCLUDE = yes?

Thanks and Regards,
Piyali

Hi Piyali,

In our build ECC_FFI_INCLUDE is set to "no"

Hi,

When i allocate memory in DSP non cache section, I get this MDMA error. However when I allocate memory in A15 non cache section, I do not get this MDMA error.

Socrates

Hi Socrates,

Sorry for not being able to get back to you earlier. This is an unexpected behavior. Could you please let us know the exact address where you are allocating the buffer and how the DSP is accessing the A15 non-cached region? This will help us understand this better.

Thanks and Regards,

Piyali

Hi Piyali,

Please ignore my post on Mar 6, 2017.

When i allocate memory in DSP, in utils non cached section i get Utils MDMA error.

Please refer mem_segment_definition_512mb_bios.7z (.xs) dated Feb 27, 2017 in this thread.

Currently i have allocated this memory in cache section of DDR to overcome this error. However i need to allocate this memory in non cached section of DDR.

Could you please help us resolve this issue ASAP.

Thanks

Socrates

Hi Socrates,

I see that the build is failing with the XS file changes over 2.10 Vision SDK release. Have you made any other changes to reproduce this issue?

Hi Socrates,

I wanted to follow up on this issue. Kindly let me know the other changes you have made over 2.10 Vision SDK to help me reproduce the issue at my end.

Thanks and Regards,

Piyali

Hi Piyali,

Apart from the changes mentioned in the earlier posts, we did perform any other changes.

Could you please provide your desk number so that I can explain the issues in a better way.

Thanks

Hi Socrates,

Summarizing the discussion here:

I could re-produce the issue at my end. The issue occurs because the IPU allocates 0xB** address for the non-cached shared region. The SBL does not map a LISA mapping which maps 0xA000_0000 to the same memory region as 0x8000_0000.

The change required is:

--- a/starterware_/bootloader/sbl_utils/src/sbl_utils_tda2xx_ddr_config.c
+++ b/starterware_/bootloader/sbl_utils/src/sbl_utils_tda2xx_ddr_config.c
@@ -500,8 +500,10 @@ static void TDA2xx_set_lisa_maps(void)
" Same memory mapped at 0x80000000 and 0xA0000000\n");
/* MA_LISA_MAP_i */
HW_WR_REG32(SOC_MA_MPU_CONF_REGS_BASE + LISA_MAP_0, 0x80500100U);
+ HW_WR_REG32(SOC_MA_MPU_CONF_REGS_BASE + LISA_MAP_1, 0xA0500100U);
/* DMM_LISA_MAP_i */

+ HW_WR_REG32(SOC_DMM_CONF_REGS_BASE + LISA_MAP_1, 0xA0500100U);
}
#endif
}

Kindly try this at your end and let me know if this works.

Thanks and Regards,

Piyali
