Denis Ahrens	f553c50b7b	ztex: if we had only errors in one round we do not count the errors to detect a totally non working fpga we only do that if the last round had some valid nonces. if we would count the errors the automatic megahertz adaption would drop and never recover.	12 years ago
Denis Ahrens	ccee686aee	ztex: precheck the secondary solutions to avoid hw errors the ztex bitstreams gives back the latest checked nonce and its hash7 value and two possible solutions. every 250ms the latest nonce is checked and compared with hash7 to count hw errors and adapt the MHz value. one change is to use the solutions even if the latest nonce is not correct. the original java ztex code also does it this way. since the second solution is often not correct we have alot of hw errors. now we always check the second solution before we submit it to the cgminer main code. the java code also ignores all hw errors 500ms after a sendHash. we now do the same. this can possibly yield in a higher MHz rate. but the chance is so low nobody will ever notice in practice.	12 years ago

Denis Ahrens	29ff10743f	libztex: check returnvalue of libusb_claim_interface() and release the interface in case of early exit	12 years ago
Denis Ahrens	e2c8a1d0f6	libztex: avoid the use of libusb_error_name() libusb_error_name() is only available in libusb-1.0.9 and newer	12 years ago
Denis Ahrens	0559d0bb6a	libztex: in case the selectFpga() failed set the selected fpga to unknown after libztex_selectFpga() failed we can not be sure which fpga is now selected. can be the old one or maybe even the new one. so set the selected fpga variable to unknown so that the next call must set it again.	12 years ago

Denis Ahrens	b48b2cc8c4	libztex: Read bitstream file in 2kb blocks with simpler and faster code optimized libztex_configureFpgaLS() like it was done some commits ago to libztex_configureFpgaHS()	12 years ago
Denis Ahrens	1203f1f621	libztex: Add firmware download support for ZTEX 1.15d and 1.15x The correct firmware file is automatically determined based on the ZTEX descriptor in the dummy firmware.	12 years ago
Peter Stuge	f967392877	libztex: Factor out local version of libusb_get_string_descriptor_ascii()	12 years ago
Denis Ahrens	90b3e6adbd	libztex: Make log messages say bitstream when refering to bitstreams	12 years ago
Denis Ahrens	d9479b2cee	libztex: Don't return error when a bitstream was already configured The high speed and low speed configureFpga functions should not return an error when no bitstream needs to be downloaded. These codepaths are not executed for now, because all calls to configureFpga set the force parameter to true. Future commits may change that, allowing cgminer to start mining immediately if each hardware has already been correctly configured with firmware and bitstream(s).	12 years ago
Denis Ahrens	b70edef9f5	libztex: Read bitstream file in 64kb blocks with simpler and faster code	12 years ago
Denis Ahrens	a5b2845096	libztex: Verify that the mining firmware is not a dummy firmware	12 years ago
Denis Ahrens	843e9120b3	libztex: Match mining firmware ZTEX descriptor against the dummy firmware The first 8 bytes are matched, which ensures that the mining firmware actually fits the hardware, assuming that the correct dummy firmware is present in the device.	12 years ago
Denis Ahrens	8d7ad82806	libztex: Start download sequence only after reading in the new firmware The download sequence starts with a reset command, which tells the board that a new firmware is about to be downloaded. The board gets unhappy if no new firmware is actually sent, so only send the reset command AFTER the new firmware has actually been successfully read.	12 years ago
Peter Stuge	584dc5acd5	libztex: Download mining firmware to all devices with dummy firmware When one or more ZTEX devices with dummy firmware are found on startup, the correct firmware is downloaded to each device, and then USB devices are rescanned until all devices have reattached with the mining firmware. This allows to discover and configure all ZTEX devices and start mining directly, without first running the ZTEX Java software to download a firmware to the device.	12 years ago

Peter Stuge	972ddf74c7	libztex: Work around ZTEX USB firmware bug exposed by the FreeBSD libusb The ZTEX USB firmware doesn't correctly support GET_DESCRIPTOR requests for string descriptors, specifically the device always returns the full string descriptor, even if the request wLength is shorter. The FreeBSD implementation of libusb_get_string_descriptor_ascii() first requests 4 (four) bytes to validate the start of the string descriptor, and since the device sends back too many bytes the USB host controller signals an error to FreeBSD which returns the error to us. In order to avoid this mess the libusb_get_string_descriptor_ascii() call is replaced with the way libusb-1.0 works; which makes only a single request to read the entire string descriptor.	12 years ago
