MRAM is totally external and the linker knows nothing about it.\r\n\r\nI did not know about View/Memory that Jim pointed out. To me the most useful thing, and what I mean by the Link Map or Memory Map is under the Debug folder (or Release folder depending on which way you are building) and is called programname.map, for example PacSat.map. It shows how much each module is using in both code (flash memory) and RAM. Here is a section showing how much code (.text in Unix terms) is being used.\r\n\r\nSECTION ALLOCATION MAP\r\n\r\n output attributes/\r\nsection page origin length input sections\r\n-------- ---- ---------- ---------- ----------------\r\n.intvecs 0 00000000 00000020\r\n 00000000 00000020 sys_intvecs.obj (.intvecs)\r\n\r\n.text 0 00000020 00048338\r\n 00000020 000046f4 Ax25Task.obj (.text)\r\n 00004714 00003d54 UplinkTask.obj (.text)\r\n 00008468 00003b14 PbTask.obj (.text)\r\n 0000bf7c 000033f0 ConsoleTask.obj (.text)\r\n 0000f36c 0000314c pacsat_header.obj (.text)\r\n 000124b8 00002b7c sys_selftest.obj (.text)\r\n 00015034 00002860 os_tasks.obj (.text)\r\n 00017894 000026b8 inodedata.obj (.text)\r\n 00019f4c 000020d0 nonvolManagement.obj (.text)\r\n 0001c01c 00002008 posix.obj (.text)\r\n\r\n=========================\r\nAnd here is how much RAM is getting used.\r\n\r\n.bss 0 08001500 00024752 UNINITIALIZED\r\n 08001500 00020000 os_heap.obj (.bss:ucHeap)\r\n 08021500 00000acc Ax25Task.obj (.bss:data_link_state_machine)\r\n 08021fcc 00000a00 PbTask.obj (.bss:pb_list)\r\n 080229cc 0000067c buffer.obj (.bss:gBufCtx)\r\n 08023048 00000360 CommandTask.obj (.bss:UplinkCommandBuffer)\r\n 080233a8 00000320 posix.obj (.bss:gaHandle)\r\n 080236c8 00000200 UplinkTask.obj (.bss:ftl0_pfh_byte_buffer$2)\r\n 080238c8 00000200 pacsat_dir.obj (.bss:pfh_byte_buffer)\r\n 08023ac8 000001d4 UplinkTask.obj (.bss:ftl0_pfh_buffer$1)\r\n 08023c9c 000001d4 pacsat_dir.obj (.bss:pfh_buffer)\r\n 08023e70 00000128 (.common:gaRedCoreVol)\r\n 08023f98 00000120 rtsv7R4_T_be_v3D16_eabi.lib : trgmsg.c.obj (.bss:_CIOBUF_)\r\n 080240b8 00000118 UplinkTask.obj (.bss:ax25_event)\r\n 080241d0 00000118 Ax25Task.obj (.bss:ax25_received_event)\r\n 080242e8 00000118 Ax25Task.obj (.bss:lm_event)\r\n 08024400 00000118 Ax25Task.obj (.bss:send_event_buffer)\r\n 08024518 00000118 UplinkTask.obj (.bss:send_event_buffer)\r\n 08024630 00000118 Ax25Task.obj (.bss:timer_event)\r\n\r\n\r\n=========================\r\n\r\nNotice that you can tell which is in flash and which is in memory by the address (080xxxxx is ram, 0004xxxx is flash).\r\n\r\nThis is totally an output file. What you changed was the link command file sys_lnk.cmd which is input to the linker. You essentially \"lied\" to the linker so it would not complain, I think. Clever way to find out how much it really wanted! But if you can send the PacSat.map (or whatever it is called), that will tell exactly who is using the memory.\r\n\r\n73,\r\n\r\nBurns Fisher, WB1FJ\r\nAMSAT(R) Engineering -- Flight Software\r\n\r\n\r\nOn Tue, Jan 16, 2024 at 12:30 PM Bob Stricklin via pacsat-dev <[email protected]<mailto:[email protected]>> wrote:\r\nJim,\r\n\r\nMake sure you are looking at:\r\n\r\nView -> Memory Allocation\r\n\r\nAnd not Memory Browser\r\n\r\nMemory Allocation should open in a TAB in a window within CCS.

You will see the package needs 154K or RAM and the Launpad has 191K. In the case of the TMS570LS0914 we have 128K max.\r\nYou can expand RAM and the subfolders and see where the memory is being used.\r\n\r\nI worked for the last few days getting a HalCoGen setup for the LS0914 and then murging this HCG file with the code of the Launcpad project. After working through some issues it built but when it ran the linker it errored out with not enough memory. So faked it out and told the linker I had more memory. Then it would build and generate a .out file and the Memory Allocation info. It matches the launch pad build.\r\n\r\nProbably need to look for ways to reduce RAM needed. Reduce buffer sizes, move buffers to external memory, or take out code.\r\n\r\nI will be looking for things here to try and complete a basic build of the code for the LS0914. Please look for ideas and post any that you come up with. We probably should target RAM usage at about 80% of the max or about 100KB. We could change processors later but that would need some study.\r\n\r\nBob\r\n\r\n[cid:[email protected]]\r\n\r\n-----------------------------------------------------------\r\n\r\npacsat-dev mailing list -- [email protected]<mailto:[email protected]>\r\nView archives of this mailing list at https://mailman.amsat.org/hyperkitty/list/[email protected]\r\nTo unsubscribe send an email to [email protected]<mailto:[email protected]>\r\nManage all of your AMSAT-NA mailing list preferences at https://mailman.amsat.org\r\n\n\n\n\n", "attachments": [ { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/?format=api", "counter": 4, "name": "attachment.html", "content_type": "text/html", "encoding": "utf-8", "size": 20177, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/attachment/4/attachment.html" }, { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/?format=api", "counter": 5, "name": "image001.png", "content_type": "image/png", "encoding": null, "size": 367151, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/attachment/5/image001.png" }, { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/?format=api", "counter": 6, "name": "PacSat_DevSW.map", "content_type": "text/plain", "encoding": null, "size": 171795, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/OASGWAQ6CBBFKZWINAAOWIMUEUVW2KT2/attachment/6/PacSat_DevSW.map" } ] }
