Firmware v1.2 with 256K sample fix

Thanks to Jawi for finding the 256K sample size bug.

Bug 1: The max sample size was set to /8 (bytes) instead of /4 like SUMP uses
BUG 2: I sanity checked the post-increment sample size (protocol +1) and it returned 1 less than 256K samples required

This firmware (v1.2) fixes that issue and seems to capture perfectly with the nightly client.

Thanks for the new firmware; will test it out asap...

Not sure if it was fixed already, but is there already support for aborting a capture?
when good software is not an alternative...

Not yet. I will try to add it soon though because it sounds like a desired feature :)

Hi Ian,

there are 512Kbit serial SRAMs "IP12B512C-T" available now.
Any plan to upgrade the Logic Shrimp?

The SUMP protocol and clients support max 256K, and the way I designed the timing and counting system makes it difficult to expand.

Maybe on a v2 with a CPLD it could work.
