Date: Thu, 18 Oct 2001 14:28:00 -0000 Message-id: <20011018161003.A3059@saturn.billgatliff.com> X-SW-Source: 2001-10/msg00192.html Guys: I was recently working with Cygwin 1.3.2, doing remote serial debugging with an ARM Evaluator-7T board using gdb-5.0. Everything was just peachy. Then I upgraded, and things got bad in a hurry. :^( Cygwin 1.3.3 seems less stable serialio-wise than 1.3.2. After several days of trying, I have yet to establish a complete serial connection with the board. And 1.3.3 also seems to require/support only hardware flow control on the serial lines, where 1.3.2 did not. I'm running on Win98SE, and can test on NT4 and 2000 if necessary. At this point, I would be happy just to be able to get Cygwin 1.3.2 back, but alas, I haven't found an archive of it anywhere on the 'net. To make matters worse, a magazine article I'm writing that describes how to use Cygwin and GNU tools for arm-elf development is set to appear in in the December issue of Circuit Cellar Ink magazine. The article was written for 1.3.2, and won't currently work with 1.3.3 unless I can figure out what's going on by next Wednesday. I really would rather avoid disappointing a new crop of Cygwin and GNU tool users. I'm developing patches for gdb-5.0, binutils-2.11.2 and gcc-2.95.3 to make them build under 1.3.3 (to fix the new export conflicts), but I haven't figured out what the problem with serial communications is. If I can't fix the problem, then the article is basically doa. A draft of the manuscript for the article is at: http://billgatliff.com/articles/gnu/gnu-arm7t/index.html . Suggestions, patches, signs of moral support, etc. would all be most graciously accepted. Thanks for the help, b.g. -- Bill Gatliff bgat@billgatliff.com
