The Problem is getting worse when disabling I and D cache. I can now start debugging the real application. This is a summary document. By using our site, you acknowledge datashet you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. But i use not ES silicon.

You could confirm the compile address of the code going into DDR, you could disassemble it with something like objdump, and walk through it. Email Required, but never shown.

If it touches some memory datashwet it may well end up datasheef the abort vector.

Allows Handling of Dynamic Exception Vectors 6. The device is running not in backup at91saam9g45. Anyone here so kind to post the initialization sequence for MT47H32M16? I checked the memory contents over and over, and they were right every time, so no luck there. MHz input, the only limitation being the lowest input frequency shall be higher or equal to 2 MHz.


It’s supported by GCC via armej-s name search for supported -mtune values here. After reset and until the Remap Command is performed, the four SRAM blocks at91xam9g45 contiguous and only accessible at address 0x Sign up using Email and Password.

Each Master has its own decoder, which can be defined specifically for each master. In order to simplify the addressing, all the masters have the same decodings I must admit SAM-BA has vatasheet into rather a cluster over the years, I’d be a lot more temped to inject code with something like Keil and tinker with bringing up the hardware that way.

And for the record i debugged in the following order: All the memory blocks can always be seen at their specified base datasheeet that are not concerned by these parameters. Figure on page 29 Figure on page 21 peripherals. Power the core, including the processor, the embedded memories and the peripherals; voltage ranges from 0.

However, some paths do not make sense, such as allowing access from the Ethernet MAC to the internal peripherals. System Controller Block Diagram Figure Still investigating but did you see anything like this or have you found a solution to your problem?

Why in steps different address for the same external register? When I recompile to run in SRAM and let it run there, it works fine, except for programming, due to the buffer being too small. In my board i solve problem – it was some problems with CLK signals routing board mistakes.

Support for Software handshaking interface. Whilst going through all timing parameters and settings I noticed the mode setting for “step 8” was wrong – it should have been 3 but was at 5.


At91asm9g45 browsing this forum: But i don’t understand why it works – “. All the Masters can normally access all the Slaves. If you have an LED you could try initializing that in the bootstrap code also, and then toggle or blink it datashret the way.

The complete document is available on the Atmel website at www. Now at a guess, I’d say the compile address is wrong, or setting up the cache, or stack, or the remapping at zero, are failing.

arm – gcc cpu and fpu config flag for Atmel AT91SAM9G45? – Stack Overflow

Sign up using Facebook. I will try your recomendations. Your past comments have been quite helpful before, hence my cry for help in this thread: Hope this can be help to someone else.

Big thanks in advance. I agree with your original comment, steps datazheet and 18 seem to disagree with the datasheet. Step into the code and see where it goes. Also, what should I use for the –with-fpu option?

I have the impression its cause should lie somewhere in the linker files, but they are the standard ones which came with the SAM-BA applet files v2. All other trademarks are the property of their respective owners.
