Part Number: OMAP-L138 Tool/software: TI-RTOS Hello. I'm trying to get IPC work on OMAP-L138 processor ( TMDSLCDK138 board). I stuck on opening Heap on the DSP core (the ARM core is the owner of the heap). Both cores are running SYS/BIOS. I'm starting a debug session, run the ARM core (it goes through the initialization and start waiting for messages) then I run the DSP core and it hangs in HeapBufMP_open loop with the HeapBufMP_E_NOTFOUND status. Could someone review my configuration and point me out what I miss? ipc_3_50_03_04 CCS Version: 9.0.1.00004 I've made custom platforms for ARM & DSP cores to avoid memory overlapping (I've also attached them)(Please visit the site to view this file)

Part Number: TDA3MV Tool/software: TI-RTOS Hi, First explain my purpose, without stopping the main chain, i need a thread to continuously receive gpio signals, like below, while(1) { receive gpio signals do something...... } I found that in rtos, BspOsal_taskCreate is used to implement pthread function similar to Linux, but I have encountered a situation, if I do not write Task_sleep(1) in the while; while(1) { receive gpio signals do something...... Task_sleep(1); } the program seems to be stuck after it is executed once, but because this line is executed, my task can only be executed 1000 times in 1 second, this frequency cannot achieve the purpose, Any comments?

Part Number: AM5728 Tool/software: Linux Hi, Am trying to sharing data between PRU2 & DSP1 core using 32kB shared memory location. Using debugger am able to send and receive data using shared memory between two cores. But as I tried same application using remoteproc approach, In which application of both cores( DSP & PRU ) run from linux side. Am not able to get communicate between two cores using shared memory region (0x4B290000) . Already define shared memory region in resource table used by remoteproc. Without defining shared memory region in rsc_table_vayu_dsp file getting following error : omap-iommu 40d01000.mmu: iommu fault: da 0x4b290020 flags but after defining shared memory location error gone but not able to see data send from PRU core on DSP core.

Part Number: AM4372 Hi This is EVM waveform when AC adopter off which our customer measured. Yellow:Input, Green: 1.8V, Blue: 3.3V 1.8V and 3.3V are power down at the same time. Do you not have any problem in this waveform? The installation device of EVM is TPS65218B1, will the falling timing be improved in D0? If this this timing is problem, please teach me how the customer should design this. Best Regards, PAN-M

Part Number: AM5728 i have an question that, the AM5728 IVA HD system when it implements the 1080p@60fps H.264 encoder. The SDK says as below: the software stack of the accelerated codec encoding/decoding runs on two subsystems: MPU subsystem on ARM-A15, and IPU subsystem on ARM-M4. Now i want to know when SDK do the 1080p@60fps H.264 encoder, the DSP C66X is in use or not? Thank you for those who help me, best wishes for you.

Part Number: PROCESSOR-SDK-AM437X Tool/software: Linux I am trying to enable to WL18xx Clock Synchronization feature on the AM437xx EVM.

What are the steps to integrate this feature into linux kernel on AM437x? Is there an updated link to the patches referenced above? Thanks.

Part Number: TDA2PXEVM hello, I follow visionSDK_userGuid_TDA2px.pdf and build the apps with parameter " tda2px_evm_bios_all " and that generate binaries files, every things are fine but i want to generate CCS projects. i read the user guides in docs and i confused. in document mention that software structure is link and chain but i do not understand who create a project and use this structure. I want to have a video capture CCS project and want to use IVA to encode video by h264. can you help me to understand software structure in SDK apps and how to generate example CCS projects?
