Working MMC driver 1739 4
Started by Deleted User
Hi,
Ok, i have been trying to get the sharp sdk MMC driver and FAT16 driver working on the Zoom starter kit...
I could get it to read a file but not write...
I have finally figured out why the sharp mmc driver will not work!
Its to do with the MMC_driver.c
in there you will find a function:
INT_32 mmcif_is_card_busy (void)
{
return 0;
}
Replace it with this one and it will work fine....
INT_32 mmcif_is_card_busy (void)
{
INT_32 i;
for(i=0;i<2300;i); //needs a delay here for ...

Nohau JTAG EMUL-ARM 1566 6
Started by colin howard
Hi All
Just wondering if anyone has any experience using the a Nohau EMUL-ARM with the SDK, in particular co-existing with BoLo / LoLo. Any guidance appreciated - at the moment we are using ours as a moderately expensive dust accumulator since it is so unreliable as to be useless.
Cheers

Migrating App to Flash on the SDK 1669 3
Started by colin howard
Hi All
What we are doing now:
Up until now our development cycle has involved building our app to load into RAM, and then using LOSH to load and execute it. After the load operation, still via the LOSH prompt, we do a couple of remaps to turn on all of the RAM, flush the cache and tlb just for good measure and then do a jump to the start of our application. Once inside our app we completely hijack the interrupt vectors so that only our code is executing.
What we would like to do:

Interfacing new displays 1620 0
Started by Deleted User
We've tried to make it as straight-forward as possible to interface new displays to our products. LogicLoader 2.x has some new features to allow for this.
If you are looking to interface a display, this document should help you along the process. You will need to be up to speed on how the specific LCD controller operates and how the adjustments to its registers affect the display timing.

Reflashing the CPLD via JTAG 1581 5
Started by futaris
Is there any way to reload the CPLD via JTAG I erased it accidentally.
I can't reload it on via BoLo / LoLo, since I've also erased flash.
Can someone supply a copy of the binary that gets flashed in via JTAG Or the VHDL so I generate the bitstream

KernelIoControl 1416 6

Hi again,
I'm am using interrupt IRQC and everything is working just fine, at least once through the application. When the application terminates and I try to rerun the program the interrupts no longer work until I reset the device. I think I have isolated the problem though... IOCTL_HAL_RELEASE_SYSINTR always fails. So the the irq to interrupt value mapping becomes inconsistent, I think. Can you help Perhaps OEMIoControl has been implemented incorrectly for IOCTL_HAL_RELEASE_SYSINTR Here are ...

Win CE 5.0 BSP version 1514 1

I'm having some trouble following the instructions in QuickStart guide.
When I download and install lpd_loce_bsp_2_0_0.zip and install it, the catalog view shows the LoCE ARMV4I BSP in Third Party/BSPs, but LoCE SH4 BSP does not appear. When I examine the catalog items, this is identified as loce.cec, version 4.2.
So it seems that either the 5.0 BSP has the wrong version attached, or I'm simply downloading the wrong archive. I chose the item under Windows CE BSP Components labeled 'WinCE 5.0 ...

Bus contention at 0x10000000.... 1502 1
Started by colin howard
Recalling this (for now). Our hardware engineer is currently taking the blame!
Hi
We have a 7A400 Card Engine plugged into our own hardware. Hanging off the bus we have an EPLD which does all the fun stuff. We have mapped this to the address range 0x10000000..0x1FFFFFFF and we are using CS1 from the SMC controller to enable it onto the bus. Before we start our code we do a remap:
remap 0x10000000 0x10000000 0x10000000
We see the CS1 signal go low when we expect it to but there appears to be...
