In the past there were (perhaps still are) MCUs which were far more resistant to such invasive techniques - and their prices were (at minimum) an order of magnitude beyond what you pay here.Īs small tech firm owner I'm as vulnerable as you.

And there are less costly methods - but perhaps the above gives you the sense of the "futility" of your (security) efforts.
Flashcode com manual#
MCU manual paints a, "too rosy picture" and neglects (entirely) the skill-level, funds, special equipment of those (paid) to defeat the ineffectual "bandaids" which this vendor (and others) employ to (try) to soothe their "less than fully aware" clients. Those who want your code - will HAVE your code - of that there is NO DOUBT! MCU vendors) are NEVER as smart, motivated, & well equipped/financed as those they (attempt) to regulate.
Flashcode com how to#
Used UniFlash application to erase flash and recover device.Ĭould anyone please let me know what I am missing here and how to do the code protection? This seems an easy problem, but haven't found any literature showing the steps clearly and producing functional result. Tried power cycling device but it remained locked. Found out it was stuck in the hard fault ISR forever loop. I tried it from main.c at run time, and the application hung. Where should this function be called from? in main.c or need another application that calls this routine? SRAM (RWX) : origin = 0x20000000, length = 0x00007FFFĪlso in main.c I created the following function:įor (ucI = 0 ucI < protect_pages ucI++)įlashProtectSet((Code_base+(0x800*ucI)), FlashExecuteOnly) I Am using CCS and here is what I changed in the linker command file:įLASH_VEC (RX) : origin = APP_BASE, length = 0x0000800įLASH (X) : origin = 0x00000800, length = 0x00010000įLASH_CON (RX) : origin = 0x00010800, length = 0x0002F800 text in another section with executable only property. I followed an application (Application Report SPMA044A – August 2012 ), and first thing was to place literals and other constants in a specific flash address with read/executable properties, and place. I would like to protect the embedded code in the micro controller, (LM4F211H5QR), from being read (executable only). Other Parts Discussed in Thread: UNIFLASH
