3 Replies and 1425 Views the next level...  1425  3 Started by  Deleted User OK, Linux boots on the Zoom card, but evidently the ethernet driver is not being invoked. I couldn't find ifconfig in the limited command set... so what next Is it a matter of passing the - ip= x.x.x.x on the exec 0x40100000 command line I tried this, but I think I've missed another step, as the link led is off. ip addr add dev eth0

3 Replies and 1461 Views Help with Touch panel  1461  3 Started by  Deleted User I am unable to get the touch panel working on the 79520 board with the LCD-6.4-VGA-10 (640 x 480) display. I've followed the steps in the documentation found on the CD, and have also followed some sample code found on the internet, but cannot figure out how to read XY coordinates. I would be grateful for any assistance or example code anyone could give. Thanks in advance.

1 Replies and 1549 Views Don't get cpld i2s DMA output  1549  1 Started by  junli On LH79520 card engine cpld interface specification &8211; page 13, 4.7 Codec I2S Interface, 2. Once the CPLD receives the bit-clock from the codec, the CPLD will generate a DMA request every sample period. I have generated and measured the bit-block signal I2S_BCK as 2.83Mhz and LRCIN signal as 44.3Khz, but I don&8217;t get the DMA request signal uP_DREQ0 at all. Please instruct is there any other register I need to set to get this uP_DREQ0 out. The CPLD version is 11.

1 Replies and 1611 Views Recover from an erased flash  1611  1 Started by  Deleted User Hi, We have about 25 LH79520 Zoom SDK with RAVEN JTAGs in an educational environment. One of the board gets the flash completely erased. I have tried the recovery procedure 'readme_rebuild_bolo.rtf' but it not worked. Then I have tried to use a flash tool 'OCDemon Flash Memory Programmer' to copy flash image from an healty board to the dead one. In all cases, the JTAG refuses to connect to the dead one, saying that 'cable is disconnected'. In the production environment, you at LogicPD might...

2 Replies and 1379 Views Why no reset signal on JTAG header?  1379  2 Started by  Deleted User According to the the documentation provided by Abatron, a vendor of JTAG emulators, ping 12 on the JTAG connector is supposed to be connected to a !RESET signal on the target. This allows the JTAG emulator perform a hard reset of the target. According to available schematics, this pin is tied to 3.3v via a pull-up resistor. The lack of this feature tends to make debugging difficult. Is there a compelling reson for the omission

1 Replies and 1384 Views ANSWER: Why slow kernel decompression?  1384  1 Started by  Deleted User Reading from flash is slow. Using a different bootloader, I found that the kernel decompression time is not so intimidating. The only difference between this other boot loader and LogicLoader is that this one copies the kernel to RAM before jumping to it. I haven't checked to see if there is an improvement when caching is enabled for the flash memory region.

2 Replies and 2181 Views Programming the LEDs and other initialization issues.  2181  2 Started by  Deleted User I'm finding that when the board is reset and the LogicLoader is not allowed to run, I am unable to toggle the state of the LEDs. According to the Logic documentation, the LED are toggled by writing to 0x55600000. This doesn't work when the hardware is reset. So, I thought that this might have to do with the SRAM controller configuration for CS5 where the address decode for this register is located. I wrote 0x10002d03 to the SRAM controller address 0x0xffff1014 (CS5 configuration). No dice. ...
