SBL2E maximums, metrics, limitations-I wants to know

[Chris Ruff]

Dear Experienced SBL2e expert out there:

How full is the FLASH when the factory SBL2e application is resident? How much room do I have left for data items?

I am assuming there is no problem programming into the remaining flash. The freescale manual states that the chip can do that.

I know the RAM is quite full, how much RAM is left with the factory app in place?

Will it be possible to add another couple of web pages with, say, a list control on one and buttons and text fields on another.

I am trying to gain some idea of whether I can use this in a design without having to buy the $300 kit just yet.

The SBL2E Serial app is about the maximum that fits in the device.
We kept adding features till we were maxed out.

We also increased the serial buffer memory to use ALL the ram.
So can you tell me more about what you want to do with the SBL2E?

One can back off from these limits, but if you app is simple you might be better off starting with
a simple app and adding what you need.

Get the dev kit and if it doesn't do what you need you can return it.



Here is the report from the factory app build....
******************************Build summary ******************************
Used 193796 bytes of 229376 availible flash (84.49%)
Used 31224 bytes of 31488 availible ram (99.16%)

I would say practically speaking probably not. I took a look at this a few months back for a customer on a tight budget that wanted to do something very similar and I ran out of flash right away. In fact I started by cutting and pasting a POST handler and that was enough to use up the available flash. It looked like I could reuse most existing buffers of RAM so I could work around the limited RAM issue. Never did get a go ahead on the project though so my experience is limited.

Thanx for replies. I have spec'd a move to the 'SB70. more better.
