Possible CPLD BUG: LEDs vs. PCMCIA 1834 12
Started by Deleted User
There is a problem with using the LEDs when the PCMCIA is disabled. When PCMCIACON == 0 then you cannot program the LEDs via the CPLD. This is true of a standalone program or from a program running under LOLO. Here is a working example showing the problem, there are four files:
demo.hdefine BOOTABLE 1
define USEPCMCIA 0
demo.lds.Sinclude "demo&46;h"
ENTRY&40;StartUp&41;
SECTIONS
&123;
if BOOTABLE
&46; = 0x00000000;
else
&46; = 0x000C0000;
endif
&46;boot &58; ...

LCD > 16 bpp? 1649 1
Started by fbergmaier
In looking at the Sharp LH7400 User Guide, they only talk about bit-per-pixel modes 1, 2, 4,8 & 16 for the Color LCD Controller. I am assuming that this means that the on-board LCD controller cannot do more than 16 bpp. Is this correct
If you need to do greater than 16 bpp, what are the options Do you need to bypass the on-board LCD controller and use an external controller chip to get better than 16 bpp
Thanks for the info in advance,
Frank

SDK-LH7A400-10 w. Linux 1819 10
Started by gzinno
I recently bought an SDK-LH7A400-10 and want to run embedded linux on it. Thanks to Marc Singer who shares lots of helpful information and patches on his website. I got linux-2.6.7-rc2.tar.gz2 from http://download.unesp.br/linux/kernel/v2.6/testing/ and patched patch-linux-2.6.7-rc2-lh7a40x-ms1.gz from buici.com. But I can't rebuild the kernel with Cygwin and GnuTools provided by LogicPD. Here are versions that may be important in rebuild:

hi all,
Firstly , Thanks Marc Singer for his great work to provide useful information and Linux support from his site..
Unfortunately, I could not bring the blob up in my LPD7A400 using the precompiled wblob.bin or self compiled blob using the patch from http://projects.buici.com/arm/lpd7a400/. According to the instructions provided , I first load the wblob.bin into the SRAM address of 0xB0000000 , and then run from this address. The blob screen could show correctly , and then i flas...

LEDs on SDK 1738 14
Started by James Zipperer
Are the LEDs (GPIO01/STATUS_LED0/STATUS_LED1) controllable through software According to the schematic, they aren't hooked up to GPIOs on the processor. That is, unless I'm on crack. I see they are hooked up to the CPLD, but can't find any info about controlling them through the CPLD.
Thanks.

U-Boot for LH7A400-10 1635 4
Started by Deleted User
Anyone out there that has compiled U-Boot for the board and has successfully got it running. We managed to get it compiled using the patches supplied to us on the ARM Linux UK list but have had no luck getting it on.
It seems to us that the ELF image fails to work, we have GCC 3.3 with gLibC 2.95 for ARM.
If anyone has a working version of U-Boot can you please send me the image, I would really appreciate it.

Is FL_VPEN latched? 1584 5
Started by Deleted User
Under what conditions would the CPLD lose the value in 0x71000000 It seems that when I set the FPEN bit, then do some accesses to the Flash memory to query the CFI, the FPEN enble bit resets.
Is there some reset logic to that bit, other than specifically writing a value into the register

JTAG: flash bus D0..D7 is being jammed 1807 6
Started by Deleted User
Hello,
I have been working with a Wiggler and the Jtag software (openwince). So far I have been successfull in connecting to the LDP LH7A400 board and reading most of the Flash memory contents.
I say most, as D8..D31 is being read correclty. However, there is some device hanging on D0..D7 and driving those bits low. I've read through the 'IO Controller Specification' and searched through the Forum messages, but there is no clue as to what this could be.
Judging from the schematics, the onl...

flash program won't boot 1558 2
Started by ylin
My program in Flash memory is located where LOLO used to be...at address 0x00040000 I believe.
On power up, Bolo executes, and it jumps straight to the program at Flash address 0x00040000.
However, when I reset the evaluation board or power it down then power it up while my program was running, I get the BOLO welcome screen instead of the program located at 0x00040000.
If my program ends properly, that is, return from main, then on the boot-up next time, i won't get BOLO welcome screen ...

When we program the CPLD on our own target board, which is mapped to use address 0x30000000, or nCS3 region of the static memory controller, the bootloader in Flash, BOLO, does not execute after reset.
The first time we power up the card engine after the CPLD has been programmed, everything is ok. I can load my software to SDRAM and execute it. However, subsequent resets result in the following messages on Tera Term:

CPLD update, how to? 1892 7
Started by mpinton
Hi,
I read PCN239 and discovered that I need to update to a newer CPLD code base. Our boards are running v3.4 (I guess, booting the board says 0x34). The only version for download is file 1000479.upd. If I place the file on my compact flash and mount the compact flash, how do I update the CPLD
I use the 'update command' I tried update /cf/1000479.UPD but that didn't do anything.
Thanks,
/michel
