Hello all: I encounter the same problem about how to update the M3 firmware which in EZSDK packages to the version TI81xx-HDVPSS-01.00.01.37 which in PSP packages(TI81XX-LINUX-PSP-04.04.00.01) on Dm8148EVM. According to the TI81XX VPSS Video Driver User Guide document ,I found that if I use the latest M3 firmware (TI81xx-HDVPSS-01.00.01.37 )，I must abide the key rules as belows : 1、use "notifyk.vpssm3_sva=0xA0000000" not "0xBF9000000(EZSDK offerd)" 2、use "./slaveloader startup VPSS-M3 ti814x_hdvpss_1G.xem3" not " firmware_loader dm814x_hdvpss.xem3 start(EZSDK methord)" 3、use “ insmod vpss.ko sbufaddr=0xA0200000” not "insmod vpss.ko sbufaddr=0xBFB00000(EZSDK methord)" execept that ,I also 1、 update the syslink and ipc and xdc to the version which fit TI81xx-HDVPSS-01.00.01.37 and TI81XX-LINUX-PSP-04.04.00.01. 2、Change the Rules.mak which in the ezsdk,and compile syslink and omx and gstomx. But,When I use gstomx (gstreamer)、omx(which in the EZSDK packages) to Play Mpeg2 video. If I do as above and use TI81xx-HDVPSS-01.00.01.37 will result the followings errors: Assertion at Line no: 445 in /home/anuo/Sdb1/Dm81xx/ezsdk5_0301_15/Myfiles/sysli nk_2_10_03_20/packages/ti/syslink/utils/hlos/knl/Linux/../../../../../../ti/sysl ink/ipc/hlos/knl/Linux/SharedRegionDrv.c: (heapHandle != NULL) : failed Assertion at Line no: 1354 in /home/anuo/Sdb1/Dm81xx/ezsdk5_0301_15/Myfiles/sysl ink_2_10_03_20/packages/ti/syslink/ipc/hlos/usr/HeapMemMP.c: (hpHandle != NULL) : failed According to http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map document,I found only the following file may be need to change: omx_05_02_00_30_1/src/ti/omx/build/MemSegmentDefinition.xs: In this file ,I change the followings section: memory[11] = ["HDVPSS_NOTIFY_MEM", { name: "HDVPSS_NOTIFY_MEM", base: 0xBF900000,--------change to 0xA0000000 len: 0x00200000, space: "data" }]; memory[12] = ["HDVPSS_V4L2_FBDEF_MEM", { name: "HDVPSS_V4L2_FBDEF_MEM", base: 0xBFB00000,----------change to 0xA0200000 len: 0x00200000, space: "data" }]; If I do this ,errors still exist.Any other things I lost? So: 1、Anyone ever test omx or gstomx(which in EZSDK ) when use the newer M3 firmware which from PSP packages( use "notifyk.vpssm3_sva=0xA0000000" methord)? If not, then how to use the omx/gstomx with firmware (HDVPSS-01.00.01.37 ) from PSP(PSP-04.04.00.01) ? 2、Which files in EZSDK need to change if I use the M3 firmware (HDVPSS-01.00.01.37 ) from PSP(PSP-04.04.00.01),or I must change M3 firmware map(I only have the bin file ,not NDA custormer)? or waitting for the next ezsdk release?
