UPDATE 2:

In order to support the new E_DMA_MSGMODE control mode on E_DMA_DWORD transfers, and to properly handle the e_dma_copy() function, an update of the ZedBoard's SD Card bitstream is required. Please follow these steps:

1. Download one of the following files:

ZedBoard+E16:

ftp://ftp.parallella.org/parallella/sd_ ... rd_E16.bin

ZedBoard+E64:

ftp://ftp.parallella.org/parallella/sd_ ... rd_E64.bin

2. Insert the SD card to a reader connected to your PC.

3. Rename the "BOOT.bin" file on the card to "BOOT.bin.bak"

4. Copy the downloaded file and rename it to "BOOT.bin".

5. Eject card, insert at the SD card slot on the ZedBoard and restart the system.

6. Copy the matmul-xx example from the esdk/examples and test.

Hello,
I am looking for the eSDK 5 reference manual.

There is a link on your site referencing to this -


But this link is broken (page not found).

Just tested this firmware on my Z64 board. Seems to be working great.

Please make sure that:
1. You use the E64 firmware, not the E16's.
2. When removing and inserting the card, you did not displaced the FMC daughtercard.
3. All jumpers are in place, following the table in the Quick Start Guide.

When you power up the board with the new FW, do you get to see the 2 penguins (Tuxes), or does it get stuck before this stage?

Any idea about how can I investigate what can be happening with the new firmware?

Thanks,

Fran

Hi Fran,
I'm sorry to hear that you are having issues with the new firmware.

Could you please boot the system one more time with the old BOOT.BIN and check if /etc/rc.local file is invoking any special script. In particular I'm interested to know if there is a clock divider script in there (lclk_div). If the script exists, please comment it out and try to reboot with a new BOOT.BIN

Thank you,
Roman.

small request: change the default target in the configure scripts to "epiphany-elf"

i assumed it would be the default and i ended up with my own computer as the target. configure --help didn't give me a list of targets so i didn't really know the target to specify. it took a while before i realized the target was listed in the build script.
