Ticket Name: Linux/TDA2: TIDL usecase on Linux
Query Text:
Part Number: TDA2 Tool/software: Linux Hi everyone, I transfered TIDL usecase from RTOS to Linux. I have a problem with execution because results of execution differ on TIDL algorithm which runs on DSP1. I checked input data in TIDL algorithm link and they are same every time so buffers are communicated correctly between links. However, output buffers are usually different with every new execution. Only when I insert in algorithm link code that print large amount of data (e.g. print all bytes of neural network structure), sometimes I get correct output. My usecase consists of same links as original TIDL usecase on RTOS. Does anyone have any idea what is happening here? Regards, Sasa
Responses:
Hi Sasa, Could you please let us know which version of SDK & TIDL version you are using ? Regards Surya
Hi Surya, I'm using PROCESSOR SDK 3.03 and TIDL 1.0.0.0.
Hi, TIDL usecase is not been tested on Linux platform. Still you can modify the usecase and run only 1 tidl link on eve and 1 on dsp and dump the input of eve and output of dsp for multiple cases assuming you are using the same input files. Can you let us know what all changes have you done to port TIDL usecase on linux? Regards, Anuj
Hi Anuj, original usecase link chain is: NullSource(IPU1_0) -> Alg_tidlpreproc (A15) -> Alg_tidl_1 (DSP1) -> Merge (IPU1_0) -> Merge (IPU1_0) -> Null (IPU1_0). Ported usecase link chain is: NullSource(A15) -> Alg_tidlpreproc (IPU1_0) -> Alg_tidl_1 (DSP1) -> Merge (IPU1_0) -> Merge (IPU1_0) -> Null (A15). As linux is running on A15 it was necessary to use NullSource and Null links on A15 core because of read and write operations with memory card. Regarding this change we had to replace BspOsal function calls with OSA function calls in usecase.We had no changes in tidlPreproc and tidl algorithm. Also, we checked in several ways content which is read from SD card and sent to tidl algorithm plugin. We used CRC on output buffer of tidlPreproc and input buffer of tidl plugin. CRC are always equal and more importantly same with every execution. However, output is always different and with adding or removing Vps_printf calls(for "debugging" purposes) can cause different behavior. For example, if we have a lot of printing on console, usecase sometimes work correctly, but if we remove all of it, it doesn't even write anything to output file. I'm sending you tidl usecase files we changed. If you can take a look and tell as if there is some problem we would appreciate that. Best regards, Sasa tidl_uc.tar.gz
Hi, wt think we narrowed down a problem a little bit. In chains_common_tidl.c file we checked function Chains_tidlFillNetParamsMem function as it is reading neural network parameters from file and write them to shared memory. It appears reading is ok. To make it easier to check parameters, we calculated CRC over those parameters. After that we checked those same parameters on DSP core where they are used for processing input image. We used here CRC again and it appears that we often get different CRC value than in function Chains_tidlFillNetParamsMem. As CRC is calculated over several different buffers which represents parameters of neural network. Interesting is that whenever CRC is wrong, that value is 0 and it is on one or two buffers, but every time it is some different buffer. More interestingly content of those "faulty" buffers are allways the same. I'm sure that CRC function is working fine. You have chains_common_tidl.c file in attachment if it is of some help. Regards, Sasa chains_common_tidl.c /******************************************************************************

Hi, Please 1st check if you are handelling the address translation properly. like if you allocates a memory from linux then before sending to any core running bios 1st get its physical address then send it. Similarly if any data comes to A15 from any other core then 1st get the virtual address of it then work on that buffer with virtual address. Regards, Anuj
