![]() If I unchecked following checkboxes then I got 0.6 s with my boot test application. Why sys/bios startup time so dramatically increases if lot of heap and stack memory is defined?ĭelay is caused by stack overflow checker. I would like to get some more knowledge why this is happening. However I noticed that increasing heap size also increases sys/bios startup time quite a lot, therefore I guess I should use only static memory allocation? Override config string stackMemory = "DDR" Ĭould you suggest what would be the "right" configuration? Currently application quite heavily relies on dynamic memory allocation and up to 80 MB might be needed. Override config string dataMemory = "DDR" Override config string codeMemory = "DDR" If just heap is increased to 80000000 it goes from 0.2 to 0.6 s. Stack size is the main cause of the delay. ![]() I got 0.2 s with this configuration: Program.stack = 0x1000 faultHeapSize = 20736000 Īnd 2.8 s with that one: Program.stack = 5242880 faultHeapSize = 80000000 My question is how to check what is actually started with boot, before main is called? Production app uses many peripheral devices and libraries I would like to find out which of them causes the long delay. There is boot library that handles quite many aspects: I thought that first call is made into main function and sys/bios stuff is started with BIOS_started, but I was wrong. map file can be seen what is called from bootloader. Therefore times can be measured very precisely.įrom. Bootloader prints something out before starting app and in app main function some pins are toggled or something is sent to serial. boot into test 670 KB sys/bios app takes 0.2 s. boot into test Starterware app happens almost immediatelyģ. boot into production 617 KB sys/bios app takes 2.8 s (it is 0.8 s if bootloader is executed via JTAG connection)Ģ. StarterWare bootloader is used as basis of the project: C:\Program Files\Texas Instruments\pdk_C6748_2_0_0_0\C6748_StarterWare_1_20_03_03\bootloaderĬurrently following tests have been made.ġ. Because 25Q032A uses clock signal up to 108 MHz and is able to use 4 bit bus, instead of normal 25 MHz 1 bit SPI. Using secondary bootloader and Micron 25Q032A flash should be one of the quickest methods. The problem is that I would like to boot C6748 as quickly as possible. The rest of it works sometimes, but sometimes you might try to hit a button but the touch registers a few i.I continue thread here, because ReinierC did not like that I have hijacked his thread: monthly statements, aging reports, time analysis, client/job P&L. Bottom 1/2" or so of the screen never registers a touch. Hi, We have a touch screen on a CNC machine on our production floor that's causing issues. Hey all,Before I get into the problem at hand, I realize this may be a multi phase problem and the document side of it may only be resolving a specific portion of the problem, but I have to start somewhere.The issue to cut off the fat and make it as simpl. Document control/access solution to prevent opening specific documents Best Practices & General IT.I actually did not know much about it (don't believe I ever used it), but there is an interesting write.
