Hi,

We have never encountered such a problem with the ATMEL reference board.
Your settings seems good... Perhaps another hardware difference between ATMEL and OLIMEX boards...

Code:
#define ETHERNET_BUFFER_BASE_PHYSICAL 0x20059000

Code:
   EMACBUF    80059000  0000E000    RESERVED

For your information, the difference between 0x2... and 0x8... addresses:
    0x2... => Physical
    0x8... => Virtual

Hi!

Having solved my previous issue, it took only a minute to face the next one.
I am using the Olimex SAM9-L9260 board. During downloading I get Checksum failure error and the CPU resets.
Sometimes it just resets during download without any debug output! No idea why!

4CA544)
****** Checksum failure on record 25, ABORT!!! ******
RomBOOT



It happened always at the same record.
I've found out that this is often caused by wrong memory settings, the ethernet buffer overlaps other regions.
I've checked config.bib and eboot.bib and increased the ethernet buffer size. It looks like it helped a little, but still I can't download a whole image (stops at 2-3-4 MB out of 6). Now Checksum failure happens randomly.

eboot.bib:

Code:

    RAM      81079000  02E87000  RAM       //modified


emac.c:

This is the original:
#define ETHERNET_BUFFER_BASE_PHYSICAL 0x20059000
starting address of the ETH buffer. The first char confuses me a little, 0x2... 0x8... I thought it means the same caused by an offset.
The buffers:
Code:
#define RX_BUFFER_SIZE           128      /* 128 rounded up */
   #define RX_RING_SIZE           240      /* max number of receive buffers */
   #define RX_RING_BYTES           (RX_RING_SIZE * sizeof(dma_desc))
   //#define RX_DMA_SIZE             RX_RING_BYTES + RX_RING_SIZE * RX_BUFFER_SIZE
   
   #define TX_BUFFER_SIZE           1536           /* 1536 rounded up */
   #define TX_RING_SIZE           16      /* max number of transmit descriptors*/
   #define TX_RING_BYTES           (TX_RING_SIZE * sizeof(dma_desc))
   //#define TX_DMA_SIZE             TX_RING_BYTES + TX_RING_SIZE * TX_BUFFER_SIZE

I also tried setting buffernums lower but it didn't help.

How should I distribute memory?

Any help would be appreciated.
Thanks!

Hi!

No progress so far. But there are a few things I don't get.
I did a comparison of the good nk.bin records and the received ones (written to the memory). I also used wireshark to check the network data too.
The original nk.bin is correct, as viewbin confirms it. Also, the traffic data is the same, correct.
After the whole record is received and stated incorrect (Checksum failed error) I dumped that record to debug screen.
I compared it to the original nk.bin (using viewbin) and there is a difference. So something fishy is going on and checksum failure it is.
Here are some tests:

I can see lots of 0050-s in the memory...
What is happening?
The address of the corrupt data is not constant, once the OS started but I couldn't repeat it again.
The question is where did the data go wrong? Out of the PHY? In the driver? etc?

BTW When I build the project I get firstboot.nb0 and firstboot.nb1, I assume compiled firstboot is larger than 4K, I only flash nb0. Is that a problem? What to do?

Thanks!
KV

Correct data is read from the PHY. The driver copies correct data to the correct memory addresses.
But after finishing the download of a record and checking the checksum the data is corrupt.

I see that always the lower 16 bits are wrong. I mean address mod 4 =(1 or 2). Not sure if it is the lower or the upper.

Please help!

Hi!
I moved the image addresses. Now there is a better chance that it works but not always.

Has anybody managed to get WinCE 6.0 running on the Olimex SAM9-L9260 board?
Please answere.

Still no luck.

I also noticed that after programming this board firstboot downloads eboot faulty. It needs a minute unplugged! I calculated a checksum of eboot after reading it from the dataflash, it gives random incorrect values after each reset. When letting it rest a while for a minute unplugged it boots ok.
I haven't encountered this problem on the 9261 board.
I also checked the firstboot source but I haven't found any fundamental difference.
