Port A GPIO and SSP 4207 1
Started by Deleted User
Hi, I am working on a SSP driver for the LH79520. According to NXP's documentation on the CPU, there is a pin called PA0/SSPEN that is available to the user. Unfortunately I cannot find any references to this pin whatsoever in Logic's documentation. Is this pin not routed to the card engine outputs or am I missing something

Unable to restore BOLO/LOLO using IAR & JTAG 2706 3
Started by Deleted User
Hi all,
I am new to 79520SDK and trying to recover BOLO/LOLO.
I erased block zero of flash accidentally and now I can recover neither bolo nor lolo.
I have IAR development kit and J-link(JTAG) in my hand but I cannot download and run any code to the board. I tried programming flash and SDRAM but none of them seems to be responding.
When I tried to write to the flash it gives "memory timed out error". I download to SDRAM but nothing appears to be coming. I thought that SDRAM should...

Using BITMAP command with Custom Display 2709 4

I'm testing the SDK-LH79520-10 with an LQ043T3DX02 (4.3" 480x272) Sharp display. I would like to use the 'bitmap' command to display images on the screen. I need to find the register settings for this display.
I found a FAQ about customizing the registers for several displays with a PXA270-10 card ( http://www.logicpd.com/support/faq/faq.phpfaq_id=139 ).
If I'm understanding this right, I need to set the correct register addresses with the correct values using the 'w' command. What w...

Hello again,

This results in some spawned makes to exit prematurely or return incorrect results (like the MAKEDEV package).

I'm evaluating the IAR Workbench IDE with Jlink (JTAG) probe for the LH79520. I'm using windows XP. I'am unable to connect to the target. Error dialogs indicate the JTAG probe is unable to correctly communicate with the ARM core.

LCD Questions 2514 5
Started by totalslacker
Hello,
I'm trying to get a STN 320 x 240 4bpp display working and the lcd controller seems to be hating me. It looks like the pl110fb.c driver is really only set up for color TFT panels, so I'm sure that's the source of my problems.
I have been going through what the driver is setting the lcd registers to and either making changes to the panel's lh_info struct or, in some case, modifying code to get it to do what looks to be the right thing (in cases where the code only supports tft panels).

Network Working ? 2409 4
Started by Deleted User
HI,
I am trying to get the networking set up
on the Zoom Cardengine.
I ran the system test which prompted me to
enter the last 3 digits of the MAC address.
I can do an ifconfig on sm0 but the system does not seem to bring up the interface
properly.
I see no 10/100 link lights on the hub
and I get a
'Partition ' light on my SMC Hub.
Cables etc are all fine.
best regards

Exclusive chip select signal for user memory mapped devices 5502 3

Hi everyone,
I am facing the problem to attach a memory mapped device our company developed to the Sharp Zoom SDK evaluation board. I got two
different card engines (LH79520 and LH79524) and the board. Since I need an exclusive chip select signal and there is an open
memory block that is free for utilization by the user I am wondering if there is a cs signal that comes out of the CPLD when I
access these addresses (referenced to in the io controller spec).
That is 0x5700 0000 – 0x57FF FFF...
