After successfully getting NTP time to work on an SBL2e with the help of this forum, I am hoping for one more success.

I'm looking to demonstrate the capability to update the software on an SBL2e using the form post method. I've got this to work on a mod 5270 (from the example 'postupdate'), however when I try to port that script over, I get a host of errors.

Is it possible and are there any examples out there? I realize there may be a problem with the available memory.

As a side question, is there a way to tell how much flash or ram memory is in use? I'm not sure what happens if I exceed the quota.

Thanks in advance.

Update from a post is not possible with the SBL2E it does not have enough RAM.

Thanks for the response. I guess I assume that if autoupdate can be done, so why not by another method to get the s19 file to the device?

I'm still unclear how I can tell how much ram/flash I have available. Can I tell from within my program? Any help would be appreciated.

The post requires that you store the entire image in ram before programming flash, so you don't have enough space in 32k. There is a lot of detail behind that fact, but this is just the way a web post works. The autoupdate is free to do it in small blocks without having the whole file available in ram.

The report at the end of the build should have the Flash and RAM stats.

Thanks for the info gents.
