1 Replies and 3501 Views Port A GPIO and SSP  3501  1 Started by  kaseldl@gmail.com 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

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".

4 Replies and 2176 Views Using BITMAP command with Custom Display  2176  4 Started by  dhaynes@midcontinentcontrols.com 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...

These instructions apply for 'Fedora Core 2' but might work for others. As i mentioned in another thread, the main problem is that some commandline tools in the supplied chrooted chain are not large filesystem aware. This results in some spawned makes to exit prematurely or return incorrect results (like the MAKEDEV package). Following steps to fix this. I had to reinstall the BDK because i couldnt get some pack...

5 Replies and 2031 Views LCD Questions  2031  5 Started by  logicpd@shannonholland.com 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). ...

3 Replies and 4972 Views Exclusive chip select signal for user memory mapped devices  4972  3 Started by  mborecky@flexim.de 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...
