Hello all, I am testing the USB gadget support for S3C2410 on a platform similar to the SMDK2410 board. I am using the patches found on: http://handhelds.org/moin/moin.cgi/HpIpaqH1940Downloads (Linux 2.6.14.3)
The test results are described below. I am sorry that it's a bit long... "testusb.c" program is used to perform the testing (The host is running Gentoo, Linux 2.6.12-r1) on g_zero. * -t9 always suceeds. * -t10 seems to _pause_ when the "Operation not supported" message is issued by the s3c2410_udc.c driver. * -t14 always fails. * Those bulk-out tests all succeed. * The first -t2 (bulk-in) test always succeed. All the following -t2 tests will fail with -110 (connection timeout). One more strange thing is that if the debugging messages of s3c2410_udc.c are turned on, M$ WinXP will recognize the board as a mass storage device, when g_file_storage is used. I can even read/write small amount of data to it with extremely bad performance, of course. When the messages are turned off, the enumeration will succeed, but XP will later claim that there is something wrong with the drive. Does this indicate a race condition? What should I check for the tests that failed? I am a newbie... I must have done something very wrong since there seems to be people running Linux with the gadget support on h1940 (S3C2410 as the MCU). Any ideas? Thanks in advance. :-) brian -- brian iMaGiNaTiOn iS mOrE iMpOrTaNt tHaN kNoWlEdGe ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
