* examples: Do not assume positive errno macrosTormod Volden2022-01-221-4/+14
| | | | | | | | | | | | | | Some functions were returning e.g. -ENOMEM and the caller would check for negative return values. However, on Haiku, contrary to modern standards, these macros are negative, so this logic would fail. In any case, change the function to return -1 instead. For good measure also set errno to the appropriate value, although it is not used in the current code. This was discovered on Haiku builds because the value for ENOMEM is INT_MIN which cannot be negated without overflow. Signed-off-by: Tormod Volden <debian.tormod@gmail.com>

* build: Prepare config.h for inclusion in examples/testsChris Dickens2020-11-271-3/+3
| | | | | | | | | | | | There are certain games played in the examples and tests source to account for differences in build environments and target platforms. This can be simplified by including config.h and using the definitions there. To that end, move the printf function attribute definition from libusbi.h to config.h and leverage it where it is used in the examples and tests.

* Fixed many compiler warnings about sign and size mismatchSean McBride2019-01-301-1/+1
| | | | | | | | | | - added various casts - added some asserts where the casts made assumptions - enabled additional warnings in Xcode project (especially -Wshorten-64-to-32) Closes #509 Signed-off-by: Nathan Hjelm <hjelmn@me.com>

* core: fix/silence issues reported by CoverityPete Batard2014-05-161-5/+9
| | | | | | * libusb has been added to Coverity at https://scan.coverity.com/projects/2180 * Use "// coverity[keyword]" to silence the issues we don't care about * All other issues from the Windows build have been fixed, apart from the closing of the DLLs.
* Misc: Revert all references to libusb/libusb.infohjelmn@cs.unm.edu2014-01-081-4/+4

* Samples: Fix timeout error on FX3 and logging improvements for fxloadPete Batard2013-04-141-11/+61
| | | | | | | | | | * Add a specific ezusb_fx3_jump() that handles timeout as a non-error This is required as a successful jump call makes the device disconnect from the bus * Set default verbosity to 1 and adjust some messages' verbosity level * Add a new -q option to decrease verbosity * Add readout of the bootloader version for FX3 devices * Filter the image types actually supported for FX3 * Fix the "errcode shadows a global variable" warning on some systems

* Samples: Add fxload sample for Cypress EZ-USB chipsPete Batard2012-09-131-0/+611
* This program was modified from the original fxload at: http://linux-hotplug.sourceforge.net to add libusbx as well as non HEX images support. * Only supports RAM upload for now, with EEPROM and FX3 support to be added at a later stage.
