Part Number: TDA4VE-Q1 Hi, TI experts HW：TDA4ECO, Customer Board Our SDK version: Linux 08.06.01.02 Rtos: 08.06.01.03 BOOT: SBL HLOS boot We are doing pressure test, 23 seconds power on, 5 seconds power off The phenomenon I described may be a bit chaotic, but the situation is really like this At the beginning, We encountered the following types of GPU error logs： 1. PVRSRV_ERROR_TIMEOUT -- can's see display on the screen -- Issue reproduce about once every 100-200 times e2e.ti.com/.../gpu_719AA852A5621995_1_2D00_0510.log.txt 2. Mismatching sizes of RGXFW_ALIGN_CHECKS_INIT -- can't see display on the screen -- Issue reproduce about once every 50-100 times e2e.ti.com/.../gpu_2D00A56219952D00D19E4F5C2D002C7B8C4ECD79C560B551_.log.txt 3. Safety Watchdog Trigger ! [358] -- continue to print this log -- can't see display on the screen -- issue reproduce about one every 200+ (the probability is uncertain, only encountered once) e2e.ti.com/.../_B0658476EE9598982D002D00_watchdog_2D00_trigger.log.txt After encountering these issues, I searched for similar issues on e2e and tried a patch, but it seems to have not improved my problem, which is a bit strange. If necessary, I can continue to test this patch in the future patch link: [FAQ] TDA4VL-Q1: What are the GPU driver bug fixes for SDK 8.6 or earlier? Then I found a post that was helpful for debugging. I removed the patch I had previously apply( ) and followed the steps in the post to capture the log: We captured the GPU debug logs by following the steps below： 1. the system will automatically insmod the pvr driver 2. run 'pvrdebug -loggroups main,mts,hwr' before run the gpu app 3. run run our app demo 4. pvrlogdump The main modification is to execute commands such as ‘pvrdebug -loggroups main, mts, hwr’ before running the GPU demo app (which we wrote ourselves). GPU demo link: caputre node -> ldc node -> (gpu...) -> csitx node I have tried to power on and off 300 times but have not encountered the previous error. It seems that a new error has appeared. I will attach the log and video： pvrdumplog: e2e.ti.com/.../pvrlogdump_5F00_2309210732.txt log： e2e.ti.com/.../_5B00_com-COM20_5D00_--_2800_2024_2D00_05_2D00_11_5F00_141349_2900_--COM20--_2800_Prolific-PL2303GC-USB-Serial-COM-Port-_2800_COM20_29002900_.log video: e2e.ti.com/.../_DE98664E_20240511_2D00_174751.mp4 normal boot log: e2e.ti.com/.../normal_2D00_bootlog.txt Please help to further debug.
