Just thought I'd let you know that there's no external ram or flash, so those guesses were completely wrong. I also doubt Michael has used a RS-232 level convertor (not everyone is going to use the uart, so it seems a bit daft to spend the cash on the convertor).Kevin_H said:I've taken the liberty of labeling everything that I could.
THIS IS JUST AN EDUCATED GUESS!!!
I'm pretty sure I'm correct on most of it.
There is external Ram and flash, I forgot the ram sits on top of the CPU, but if you look at the spec sheet for the OMAP, it doesn't have any internal Flash. So a flash chip is needed to store a kernel image or at least a simple SD card bootloader.Squidge said:Just thought I'd let you know that there's no external ram or flash, so those guesses were completely wrong.

Also, does this thing fry fish? Just wondering about the "batter charge"![]()
My post wasn't phrased in the best way, by "external" I meant somewhere else on the board. Both ram and flash are actually on top of the omap (It's a combined ram+flash setup, not seperate chips for each).Kevin_H said:There is external Ram and flash, I forgot the ram sits on top of the CPU, but if you look at the spec sheet for the OMAP, it doesn't have any internal Flash.

Now thats a possibility.Kevin_H said:Second I believe that the RS-232 converter is for Debug and board bringup purposes, it will be removed once the design has been proven.
The LCD controller *is* internal. However, the omap can't drive an LCD directly, therefore a buffer is required.Kevin_H said:What I labeled as EXT Ram is most likely the LCD controller. (I thought the LCD controller was internal and the Ram was external, I probably should have looked at the spec sheet first for the OMAP)

Don't be too harsh on the guy, he's only tryna help us electronic noobs.
I didn't know that the flash was included in the ram chip, thats pretty sweet. The team is pretty lucky that this is TI's pet project otherwise parts like the RAM/FLASH chip and CPU would be pretty dam expensive in low quantities, if not impossible to get.Squidge said:My post wasn't phrased in the best way, by "external" I meant somewhere else on the board.

Yeah, it all looks nice. I'm looking forward to seeing all of that silicon and plastic actually do somethingargor said:nice pixson the blog
and @ Squidge congrats on being a new mod
hope you don't let the ban power temp you![]()

I thought Squidge had a different avvy. But no one was mentioning that he was a mod, so I thought that maybe you could have that avvy and still not be a mod or something.argor said:and @ Squidge congrats on being a new mod

Yup, I know. I just wanted to make sure people didn't get the idea that they could remove that chip and replace with a bigger one to get more memory.Nova said:Don't be too harsh on the guy, he's only tryna help us electronic noobs.
