4 Replies and 1244 Views Card Engine to SDK board schematic clarification  1244  4 Started by  steve My LH7A404-11 Card engine schematic shows CD_GND of U13&9114&93 going to J1B&9180&93. On the SDK, J1B&9180&93 is the RTCK, going to the JTAG J36&9111&93. The lines on both boards do match the schematics. 1. Is sharing the JTAG RTCK line with the CD_GND intended 2. I don't see the JTAG RTCK line going anywhere else on the SDK brd other than from J1B&9180&93 to J36&9111&93, so am unclear of your implementation. I'm sure U13 could care less about the JTAG line, so can I assume the LH...

I will soon be ibtaining a ZOOM BlueStreak Ah404 Development Kit from Logic PD. this product does not come with an LCD panel or touch screen controller. but Logic OD sells ZOOM display kits. these are too expensive for our project and out of our reach. However, we do have remnants and excesses of Sharp TFT LCD panels, one with an added touch screen controller and one without one. The one without the touch csreen controller operates on a 24 bit interface. The remaining operate on an 18 b...

It was after I install a new video card (matrox dual head) and updated the ethernet driver (VIA RHINE II). It has been working for an year and a half. Same scripts, same everything. The problem. I use teraterm to bring the nic up. Then, I download the image, and then boot. But now, the image boots, but it does not finish the process witht he PB 5.0. The image initializes the screen, but it stops there. Just before Windows screen. Inside PB, ...

2 Replies and 1104 Views PCMCIA support from LH7A404 CardEngine  1104  2 Started by  Deleted User I am considering this development system for a new project. Among other things, it will need to support PCMCIA 5V device cards. The specs mention PCMCIA signals being available, but the CF slot being 3V3 memory only. Please advise what we need for PCMCIA support Hopefully someone has already solved this problem, if we can buy a built up adaptor of some sort for immediate evaluation, that would be excellent. Failing that, are any schematics availabe for a proven design Thanks, Rick

3 Replies and 1249 Views LH7A404 and CSTN LCD based on vxWorks winML  1249  3 Started by  Deleted User Hi, I use a VGA, CSTN LCD to interface the LH7A404. Select the vxWorks as RTOS. Normally, the LCD image is right. But if I access the others memory such as flash, CPLD space, the image would show chaos. The LCDframe buffer is in the SDRAM malloced by cacheDMAmalloc(). The SDRAM is bufferable and cacheble, and the flash or CPLD memory space is not bufferable and not cacheable. I guess this problem is bus conflict, but the LH7A404's UG indicate the LCD AHB has priority to access the SDRA...

I basically have two options: 1. Use an LH7A404 card engine. 2. Make my own card board, which would be better for me, but requires the kind assistance of one of the hardware engineers in here.

8 Replies and 1174 Views LH7A404 stays resetted after blanking flash!!!  1174  8 Started by  Deleted User This problem araised after accidentally erasing the Flash memory. We thought it was a Jtag problem (becasue we could communicate with the board), but now we are sure that's not the case. Here's the situation: When I measure voltage in the reset pin of the Jtag interface (that's directly connected to the reset of the microprocessor, and to a pin in the CPLD), I get 0.2 Volts! Since this input is asserted when set to a low state, we think that the microprocessor is reseted therefore not ...

6 Replies and 1119 Views Flash animation  1119  6 Started by  Deleted User Hi All, I have the SDK running using the WinCE 5.0 sample binary on a display. Would like to eventually bring up flash animation. Full WinCE 5.0 comes with Media 9 Player. Has anyone tried to run animation on this SDK Trying to get an idea if its even possible before taking the next development steps. This SDK is running a 200Mhz processor. Would the 266Mhz processor be needed Does Logic plan to release a card engine with the 266Mhz processor Thanks for your help!

We are connecting as recommended in UserGuide LH7A404 from Sharp (page 83 Fig.4-3) using Address line A20 as ALE, A21 as CLE, I/O0..I/O7 (data0,...,data7). The biggest problem arises when trying to connect NAND Flash Chip Enable: in your schematics you are using PC6 as Memory Bank Selector (logic implemented in CPLD with a couple of OR Gates and nWE and nRE lin...

1 Replies and 1143 Views Production programming howto. Serial bootload->LOLO->W  1143  1 Started by  Deleted User Things are completing and need to think more about how to perform the production programming. I think the best would be to put the cpu in serial/uart boot mode, download a small bootloader that in turn will download lolo. Then let lolo take over download the CE image through ethernet. It would be nice to get rid of jtag downloading. But, does there exist a ready-made serial bootloader somewhere that will accomplish this At least until things are stable enough and volume high enough that we wi...
