Ticket Name: TDA2EVM5777: visual-sdk example: messageq_single.xem4 - where is the source code?

Query Text:
Part Number: TDA2EVM5777 Other Parts Discussed in Thread: TDA2 Hello *! I've got some trouble bringing up an "unusual" use-case on the TDA2-5777x eval board. I'm fighting with remoteproc booting the subcores with customer code compiled by gnu-toolchain. So far, I'm able to compile working code (checked with ccs and JTAG, binary load...), but something is throwing the error: "Data Access in User mode during Functional access" I didn't change the dts - stuff, so there must be something wrong in the custom build code. I would like to take a look to the "well running" code example, called: messageq_single.xem4 ...but: I can not find the sources... I grepped through the hole visual-sdk, nothing! No "cmd" or other file containing this name. I removed all "*.xem4" binaries -> "make clean all" after that... no "xem4" files have been build. I would be glad to take a look into "how this well running code" have been compiled... It's necessary to find the errors in my own code, which based on a "non supported" GNU-Build Makefile build environment, which will allow real bare metal programming of the subcores, without any "SYS/BIOS" or RTOS fragments. It's a hard job, I know! But I would be glad if I can lean on something existing, which works in another environment... Just to prohibit reinventing the wheel... TNX - Marco.

Additional information about the L3 custom Error: FIRST: omap-iommu 58882000.mmu: iommu fault: da 0x0 flags 0x0 THEN after a while (some reboots of M4 core): 44000000.ocp:L3 Custom Error: MASTER IPU1 TARGET GPMC (Read): Data Access in User mode during Functional access What does that mean? Where to look out for the reason of this error?

Hi Marco, which is the version of your VisionSDK? Regards, Yordan

The basis of my development ist the linux 4.4.45. I took it out of visual-sdk 2-12-02-00, which I have fully extracted on hdd. My code is running completely outside of the SDK and I'm not able to use CCS for development. We got a very special requirement running Linux on A-15 cores and using remoteproc to bring up "Real Bare Metal" Code, without BIOS or RTOS, on the subcores. It must be something different using JTAG with CCS (and it's gel scripting...) on one side and dealing directly with remoteproc, the MMU-Stuff and linker Scripts, Remoteproc-Headers... on the other side. The code generated by the arm-linux-gnueabi-Toolchain works on M4, if loaded and jumped directly with CCS over JTAG. Uploaded by remoteproc the error above occurs. (Of course I'm using the custom header file for implementing the resource_table for remoteproc, which is tuned with the linker - file "tda2.lds" and an ARM startup code... I also tried out the ducati-startup code: Core_smp_asm_gnu.sv7M, but the error remains...) There is one special *.xem4 which is running perfeclty... it is the messageq_single.xem4... but this is not build in the SDK, it is only a copied binary and I am looking for it's building mechanism... maybe I'm able to find my mistake at least... hmmmm. CU (tmw) Marco....

Hi Marco, I have forwarded your question to VisionSDK experts. Regards, Yordan

Hi I think messageq_single.xem4 is from IPC package. The source code for IPC examples shall present in the \ti_components\os_tools\ipc_3_43_03_05. But I guess you need Bios running on remote cores to work these IPC examples. I guess a better solution for you may be to use uboot to load the remote core binaries intead rproc of IPC. regards, Shiju

Hi @Shiju! ===============> ADDITIONAL INFORMATION // NEWS: I reverse engineered some fragments of the binary above using readelf. I've seen how the MMU mapping is done...

Why? Can you tell me something about the error above? THANK YOU for your help .... M

Everything I tried leads into one of two errors: (1) omap-iommu 58882000.mmu: iommu fault: da 0x0 flags 0x0 or: (2) L3 Custom Error: MASTER IPU1 TARGET GPMC (Idle): Data Access in Usermode during Functional access And I am really not able to find out something useful for my use-case when I examine the "ipc..." sources. I do not find, where and how the "xem4" files are build. Of course... there is somewhere a messageq_single.c ...but -> maybe there must be some "pixie dust"... gluing everything together? So here's my question again: I run linux on A15 core. I have to re-use C6x and Cortex M4 code from our other projects and the best way of managing firmware of the subcores is using remoteproc. I use the gnu-linux-eabi toolchain and my editor is not a IDE, it's vi, because I have to understand how the code we will provide "EXACTLY" works. I can not provide any kind of "black box" to my customers, because of the certification we need. What works: I got a Makefile using arm-linux-gnueabi... creating some kind of code using the tda2.lds file, the ARM-startup-code (tried out startup_ARMCM4.S and Core_smp_asm_gnu.sv7M) and of course custom_rsc_table_omap5_ipu.h... I tuned everything together and I am able to configure the MMU rudimentary. But something is missing... leading into one of the two errors shown above, no matter what I try. Without a working example, at least without a working startup code, some kind of baseline... I am not able to reach the point, from which I can do what is my main job: Porting our Code into the new Board design... The usage of linux on A15 instead of RTOS or BIOS makes the usage of the MMU necessary and handling it is obviously not ease... I need help here.... TNX Marco

Hi, The first error you mention: (1) omap-iommu 58882000.mmu: iommu fault: da 0x0 flags 0x0 Indicates an MMU fault at IPU virtual address 0x0. Based on the original remoteproc logs, I see that virtual address 0x0 was not being programmed in the MMU. The IPU expects the vector table at address 0x0. I see that later, you have added virtual address 0x0 to the resource table, and it is getting mapped. So it seems like you are past that error? For the IPC messageq_single example, the files of interest would be: packages/ti/ipc/tests/messageq_single.c --> source code for test packages/ti/ipc/tests/IpuAmmu_vayu.cfg --> AMMU config, used by SYS/BIOS to configure the AMMU (UNICACHE MMU) (remoteproc doesn't do this) packages/ti/ipc/remoteproc/rsc_table_vayu_ipu.h --> Resource table, used by remoteproc for programming the MMU and setting up IPC packages/ti/ipc/tests/package.bld --> build file Thanks, Angela

I took a look into the ELF file (objdump) and found out, that the "Pragma" I have to convert to GNU-Style (__attribute__'s) something went wrong. After that I have fixed the linker script... in the provided lds the section of rst_vectors and startup code is not where it belongs. Than I had to fix the "far jump" Problem by fixing the way to jump into "main" and "setup" of the C-Code... and now I am able to bring up M4 with a very simple example. That is what WE NEED: Only as much code as necessary to start work on M4 subcore. BUT... such a example would be nice for everyone who wants to code on TDA2 subcores on its own, without being in the jail of the TI SDK, which links "across country" through much different directory... a little bit of XDC here, calling SYS/BIOS there... including some code (!) generated by configuration process... it is hard to brake out of this jail and this can not be the goal of an BSP (!) which should help bringing up a system in the use case of the costumer. So I'm a little bit surprised and be afraid of the future, when complex drivers of MIPI or other L3 Peripherie have to be ported from TI-SDK into our own, bare metal world... ;-) Best regards: Marco...
