2 Replies and 1799 Views Interfacing new displays 1799 2 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.

0 Replies and 1661 Views Initializing GPIO ports J and M 1661 0 Started by maslo I'd like to utilize GPIO ports J and M, more specifically bits PJ0:5 and PM4:6. I know those pins are multiplexed with another function, and I have found a mention about MUXCTL registers but I can't find, which values write to those registers to enable these pins. According to supplied libraries I think that writing and reading those registers is no problem (gpio_write_byte and gpio_read_byte) but really got stuck trying to solve this problem. Thanks for any help (a piece of code would be great:...

3 Replies and 1601 Views Loading an image into RAM 1601 3 Started by maslo I want to load an ELF image file into RAM. When the file size is under approx. 280 kB, everythings ok, but when I loaded an image of size 350 kB and tried to execute the program using "jump" command, the program didn´t do anything. The thing which made me confused is the message I got from the LOLO: loaded 198016 0x200c0000 Ram ignoring rest of file...done md5sum of _loaded_ portion of the file: ... This is shown to me everytimes I am attempting to load a file into ram, but it never...

3 Replies and 1549 Views GPIO port B pins 1549 3 Started by maslo I need to connect some interface to GPIO port B. According to pin names in MCU documentation I was trying to localize those 8 pins on SDK board expansion headers. I did it for 6 of 8 pins, but I can't find the resting 2 pins. Their name are uP_I2S_SWS (MCU documentation name is PB2/SSPFRM/I2SWS) and (uP_I2S_BCK). Nowhere in schematics I can find a pin whose name is at least similar to those given above. Does anybody know, where's the problem Thanks

5 Replies and 1602 Views Does LH79524 support 32 bit External device ? 1602 5 Started by Deleted User I need to be able to interface to an external bus device that is 32 bit wide data. Can the LH79524 do this Can your kit board do this I think the data sheet says so, but the Logic kit board says 16 bit I think. So is this just a limitation of the kit board or the part

3 Replies and 1659 Views Compact Flash 1659 3 Started by bethel Hi. I am working with the LH79524 development board, and I am trying to write my own custom Compact Flash driver. I am writing the driver for memory mode only, and I am setting my base address of the registers to 0x48200000 as per the IO specifications. Therefore my registers are between 0x48200000 and 0x4820000F. However when I try to write to these registers, they don't seem to change. Since the CF signals seem to be abstracted by the CPLD, I was wondering if there is some functions or c...

5 Replies and 1604 Views Problem Writing to Flash 1604 5 Started by tlucas I am struggling with a driver to write to the flash (no Lolo involvement) which does not seem to be co-operating. When I send a Common Flash Interface Query then I get the QRY string back so I have communication at at least a basic level. When sending an unlock command for both banks then the returned status word indicates that it was a success. Blanking sectors returns a success in the status word but writing words does not. However, when I examine the flash I find that nothing has been writ...

1 Replies and 1649 Views LogicLoader net commands missing (ifconfig, ping, ifmac) 1649 1 Started by noonan I've tied lolo versions 1.6.1 and 2.0.3. Both are lacking the net related commands present in the LH7A404 lolo. Specifically the ifconfig, ifmac and ping commands are missing. Is there an alternative that I have missed If not, are there plans to add these commands Being able to load a large elf from a tftp server is really nice and this can't be done without an IP address.
