But i don’t understand why it works – “.

Support for Software handshaking interface. Download datasheet 2Mb Share this page. Each Master has its own decoder, which can be defined specifically for each master. It’s supported by GCC via armej-s name search for supported -mtune values here. Post as a guest Name. Users browsing this forum: The complete document is available on the Atmel website at www. This is a summary document. Once again, thanks a million!

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. I can’t work with this DDR2.

I must admit SAM-BA has turned 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.

Still investigating but did you see anything like this or have you found a solution to your problem? Signal Description Table 21 gives details on the signal names classified by peripheral. System Controller Block Diagram Figure The device is running not in backup mode. Automatic wakeup on trigger and back to sleep mode after conversions of all M k 11 Email Required, but never shown.

Allows Handling of Dynamic Exception Vectors 6. Have you checked your voltages under load?

Big thanks in advance. Microchip AT91SAM9G45 embedded microprocessor is designed to provide a highperformance processor solution with high flexibility for general and multimediaoriented applications. SAM-BA monitor however could really use a make-over, because it lists random values I am building arm-eabi-gcc with gcc 6.

Now i solder samsung memory At91sam9y45 and all seems fine.

The Problem is getting worse when disabling I and D cache. Why in steps different address for the same external register? At91sam9g45 datasheet pdf 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.

Power the core, including the processor, the embedded memories and the peripherals; voltage ranges from 0.

All the memory blocks can always be dafasheet at their specified base addresses that are not concerned by these parameters. Bing [Bot] and 1 guest. With a better grasp of what the hardware is actually doing or not-doing, you might have a chance at getting SAM-BA up.

As for distinction between –with-tune–with-arch and –with-cpusee this answerTLDR is that –with-cpu is preferred.


If you have an LED you could try initializing that in the bootstrap code also, and then toggle or blink it along the way.

In my board i solve problem at91san9g45 it was some problems with CLK signals routing board mistakes. If you can confirm the code downloaded to DDR is valid, with say a CRC32 check compared to a value computed on the PC, and can repeat that a couple of minutes later, it would suggest the memory is indeed intact, and can refresh properly.

Hope this can be help to someone else. Although after using it for a while longer i’m noticing some strange things, for example if i try to copy a large file to memory i datashest a kernel panic and the board reboots.

After reset and until the Remap Command is performed, the four SRAM blocks are contiguous and only accessible at address 0x Also, what should I use for the –with-fpu option? 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.

Would you happen to have any clues as to what the cause could be? Step into the code and see where it goes. You at91samg45 confirm the compile address of the code going into DDR, you could disassemble it with something like objdump, and walk through it. Elcodis is a trademark of Elcodis Company Ltd.
