Tool/software: TI-RTOS

Hi, I'm using AM572x custom board.

I tried to build an IPU STB example provided by TI (tiSTB-MacFilter.tar.gz),
but an error occurred and it was not done.

I think the IPU STB example and the PDK do not seem to match.

Hi Kim,

I am not sure where you received the IPU STB example. You may follow the STB release note to try building with default PDK version, then move to the latest PRSDK 4.3 software-dl.ti.com/.../index_FDS.html with PDK 1.0.10.

Garrett

Hi Garrett,

I received a 61850 design PDF from the TI homepage.

And there is an example of IPU STB.

AM572x_IEC61850Design.pdf

PDF Title:

TI Designs
Packet Processing Engine Reference Design for IEC61850
GOOSE Forwarding

Contents:

5.8 Build Application
To build the application:
1. Clone the application source code from git.ti.com/.../tidep0074
$ git clone git://git.ti.com/apps/tidep0074.git
2. update products.mak
3. $ make
The app_host is generated under host/bin/release/, server_dsp1.xe66 under dsp1/bin/release/ and
server_ipu1.xem4 under ipu1/bin/release for testing.

Best Regards,

John Kim

John,

The TI design was based on Processor SDK 2.0.2 (software-dl.ti.com/.../index_FDS.html ) and is expected that some compilation and link issue may happen if migrating to the recent PRSDK. You may go ahead to move to the latest PRSDK 4.3 and see if any issue comes up. Some of APIs in PDK packages\ti\drv\icss_emac\src\icss_emacDrv.c may have been changed then the icss_emacDrv.c in the example may need update accordingly as well. Any background that you are interested in the example?

Regards,
Garrett

Garrett,

To be in charge of IEC 61850 Stack in ARM, the network load is too large.
Therefore, it is efficient to handle the Ethernet Packet by the PRU in charge of 61850 Filtering from the IPU.

And I am interested in IPU STB example to apply TI-RTOS HSR / PRP solution.

John Kim

Garrett,

I tried to build with PDK 2.02.
The build worked normally without error.

However, when you run the image, the following error occurs :

I have question.

Which area of memory is the (L3_EMIF_SDRAM 0xA0000000) area of rsc_table_vayu_ipu.h?

0xA0000000 is external ddr ram area on the AM5728.

#define L3_EMIF_SDRAM 0xA0000000
#define IPU_EMIF_SDRAM 0x10000000

.........

{
TYPE_DEVMEM,
IPU_EMIF_SDRAM, L3_EMIF_SDRAM,
SZ_256M, 0, 0, "IPU_EMIF_SDRAM",
},

Best Regares,
John Kim

The L3_EMIF_SDRAM 0xA0000000 area in rsc_table_vayu_ipu.h is as you indicated - DDR3 RAM, and mapped to virtual address to 0x10000000.
Do you use the same Linux kernel from Processor SDK Linux 2.0.2 and do you have issue to run the default ex02_messageq example from IPC?

Garrett

Garrett,

In the IPC example, it works normally.
However, in the IPU STB example, an error occurs.

probably i think seems to be a problem with rsc_table memory area.

ipu1_cma_pool: ipu1_cma@95800000 {
compatible = "shared-dma-pool";
reg = <0x0 0x95800000 0x0 0x2000000>; //32M
reusable;
status = "okay";
};
cmem_block_mem_0: cmem_block_mem@a0000000 {
reg = <0x0 0xa0000000 0x0 0x0c000000>;
no-map;
status = "okay";
};

John,

Why do you have to update the dts and rsc table and not use the default one from the example project? Also do you have 'Resource.customTable = true;' in your .cfg file?

Garrett

Garrett,

In the IPU STB example, the default setting is resource custom table = true.

"/ * Enable Memory Translation module that operates on the BIOS Resource Table * /
var Resource = xdc.useModule ('ti.ipc.remoteproc.Resource');
Resource.customTable = true; "

The reason why I am not using the default setting of example,
1. I can not allocate 256 MB of DDR memory to the IPU. (256MB is too large)
2. I will use the memory area of CMEM.

Regards,

John Kim

John,

You may exercise the original project on AM572x IDK and modify the CMA and CMEM size only to see if it still crashes, and then port to your custom board. The application doesn't really use such large size memory 256MB, so it should allow you reduce to 32MB without issue. CMEM is always used in the application. After updating size (not address) in dts, make sure to rebuild and use the new .dtb.

Garrett

Garrett,

Thank you for your reply.

I tried changing the memory area. The IPU STB example is the default setting.

In the CMEM Region assigned by Linux, The IPU uses the Ethernet Packet area.

1. CMEM area

cmem_block_mem_0: cmem_block_mem@a0000000 {
reg = <0x0 0xa0000000 0x0 0x0c000000>;
no-map;
status = "okay";
};

2. IPU1 Resource table

{
TYPE_DEVMEM,
IPU_EMIF_SDRAM, L3_EMIF_SDRAM,
SZ_32M, 0, 0, "IPU_EMIF_SDRAM",
},

3. Error Log

IPUSTBEX_ERR.log

John,

Is this the Linux kernel from PLSDK 2.0.2? You may try to comment out icss_tx() and icss_rx() from Server_exec() to check if the addresses are correct:

pRxPkt0 = (UInt32 *)(msg->RxPhysAddr[TEST_PORT][0] + VIRT1);
pRxPkt1 = (UInt32 *)(msg->RxPhysAddr[TEST_PORT][1] + VIRT1);

These addresses are allocated from Linux CMEM and transferred through IPC to IPU.

Note the pRxPkt0/1 address is virtual address with the translation +VIRT1 which is defined as

#define VIRT1 (-0x90000000U) /* PA 0xA0000000<->VA 0x10000000, see RSC table */

Thus with your
#define IPU_CMEM_IOBUFS 0x85000000 //=> virtual address of the DSP memory section
#define CMEM_PHYS_IOBUFS 0xA0000000 //=> physical address of the CMEM (shared) memory section
the VIRT1 need to be re-defined accordingly.

If the pRxPkt0/1 are correctly set, then you may have to dig into icss_tx() and icss_rx() to try narrow down where the exception occurs.

Regards,
Garrett
