Hi all, I am having really strange behavior, which I could not explain to myself. When I do a copy from 0x20208A10 to 0x20487382, all the content is copied. ...
It is processor specific ….. (ARM that is) ________________________________________ From: AT91SAM@yahoogroups.com [mailto:AT91SAM@yahoogroups.com] On Behalf...
Actually, I do not believe it is a compiler question, I believe it's a valid ARM implementation question. Mis-aligned word reads will not read what you expect...
Thanks for the answer microbit, Therefore I enabled the alignment checks on addresses. But I still do not understand why there is such a thing in ARM. Why...
Hi, From: AT91SAM@yahoogroups.com [mailto:AT91SAM@yahoogroups.com] On Behalf Of ICLI, Bekir (EXT) Sent: 02 June 2008 07:30 To: AT91SAM@yahoogroups.com Subject:...
... Yes and no. It's in the hardwiring to the ALU. To read 4 bytes in go, you need the lowest 2 bits to address byte 0/1/2/3. So, you can therefore only...
Kris, ... Only 68020 had this, 68000 and 68010 didn't, you just got an Address Error. The 030 was an 020 with an MMU and tolerated misaligned loads. The 040...

Hi All, I recently bought Olimex SAM7EX256 board. When I connect it to the USB port, it is not getting recognized by the WinXP. If I start SAM-BA v2.6 and try...
Dear All, In Reset state for AT91SAM7S256, all the I/O port will be active High by default. Is there any possibility we can change to low state for I/O at...
Hi all, I've seen in the manual of AT91SAM9RL64 such a statement: "The SD Card, NAND Flash and DataFlash downloaded code size must be inferior to 56 K bytes." ...
Because these 12K is reserved for level one bootloader program, which browses external memories, detects and downloads your code from flash to RAM. S...
It doesn't work when powered from USB, you need to use an external power supply. 1. Switch the board's power supply jumper from "USB" to "EXT". 2. Apply power...
Hi! Im a newbie in ARM7, and I have a problem when i use UART on AT91SAM7X256 uC in CrossWorks 1.7 (my board is an Olimex SAM-EX256). I can send characters to...
Check the pointer going in for validity (it it reasonable?) Single step uart0_puts at the instruction level and examine the addresses being used. -- Paul...
Thanks for your suggestion. I checked it, and the pointer points at the same address in the uart0_puts() function like the one with which I call this function...
David, Below is a piece of code that I am using to display the address of the instruction that cause the Abort. On my board, I have a LCD display, but you can...
Hi, Thanks for replying.I tried changing to external power supply, but there is no change. SAM-BA still gives the same message 'Failed to open connection'. Is...
Thank you all who tried to help me, I solved the problem. Its a shame that I had this mistake which is usually taught on the first programming lesson. I used...
Actually, I could not pull low the signal, because my system have the power chip using active low to shutdown. If I put pull down external resistor then the...
Hi, I am using KEIL compiler for my SAM7SE512. We have quite a bit of code developed for this project & now all of sudden when I implemented some more...
I got it working. I think the problem was with JTAGSel jumper. Once I removed that jumper, Windows recognised the board as Atmel and I am able to connect to it...
Hello, 1) Is your KEIL compiler version is code limited? 2) Temporarily remove some other functions / code to make more space then run the offending function...
Hi I am using at91sam9260 and i am trying to compile glibc 2.3.5 with nptl support for this board . I am not been able to do it as there is no patch for the...
