| | | | | | | | | | | | | Add a check to validate the selected channel/interface, which not even libftdi seems to do yet. This patch changes default behavior: the new default channel/interface is A. Also, this patch uses the word 'channel' in addition or in place of 'interface' where possible without too much hassle because it is the term FTDI uses.

* Let the programmer driver decide how to do AAI transfershailfinger2012-06-151-0/+1
| | | | | | | | | | | | | | | | | Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now. A patch which utilises this abstraction in the dediprog driver will follow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://www.goepel.com/en/jtagboundary-scan/hardware/picotap.html This device is actually a JTAG adapter, but since it uses standard FT2232 A interface pins, it can be easily used as SPI programmer (tested it here successfully). PicoTAP supports only 5V output, so one needs to reduce this to 3.3V in a same manner as DLP Design DLP-USB1232H, see http://flashrom.org/FT2232SPI_Programmer#DLP_Design_DLP-USB1232H for details. The PicoTAP pin-out is as follows: PicoTAP | SPI ---------+------- TCK | SCLK TMS | CS# TDI | SO TDO | SI /TRST | - GND | GND +5V | VCC, HOLD# & WP# after 3.3V regulator I managed to run PicoTAP in 10MHz, 15MHz and 30MHz modes (by forcing DIVIDE_BY), against SST25VF016B SPI flash, read/write/erase all worked fine (write seems somewhat slow).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to TIAO/DIYGADGET for sponsoring a test device! This is an FTDI FT2232H based device which provides an easily accessible JTAG, SPI, I2C, serial breakout. The SPI part can be used to flash SPI flash chips using flashrom. http://www.diygadget.com/tiao-usb-multi-protocol-adapter-jtag-spi-i2c-serial.html http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User%27s_Manual#SPI_Connector_1 There are two SPI connectors (pin headers) on the board: SPI1, which is connected to the FT2232H's A interface, and SPI2, which is connected to the chip's B interface. Both can be used to flash SPI chips: flashrom -p ft2232_spi:type=tumpa,port=A flashrom -p ft2232_spi:type=tumpa,port=B The default interface is A, so for SPI1 you can also just write: flashrom -p ft2232_spi:type=tumpa I tested all operations on both interfaces, everything works fine.

| | | | | | | | | | | | | | | | | | In order to make the ft2232_spi code more usable in libflashrom (e.g. from frontends/GUIs) there must not be any exit() calls in the code, as that would also terminate the frontend. Thus, replace all exit() calls with proper error handling code by returning a _unique_ negative error number, so that the frontend (and/or user/developer) can also know a bit more exactly _which_ error occured, not only _that_ an error occured. Also, call ftdi_usb_close() before returning due to errors.

* kill central list of SPI programmersmkarcher2011-05-111-3/+15
| | | | | | | | | | | | | | | | | | Remove the array spi_programmer, replace it by dynamic registration instead. Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").

* Programmer debug messages during programmer init/shutdown are usefulhailfinger2010-01-071-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | because they print hardware settings and desired configuration. They help in getting a quick overview of hardware and software state on startup and shutdown. Programmer debug messages during flash chip access are mostly a distraction in logs and should only be enabled if someone is having problems which are suspected to stem from a programmer hardware or programmer software bug. Disable those messages by default, they can be reenabled by #define COMM_DEBUG in the affected programmer file. An added benefit is a tremendous size reduction in verbose probe/read/write/erase logs because only flash chip driver messages remain. In some cases, logs will shrink from 65 MB to 10 kB or less. The right(tm) fix would be two different debug levels (DEBUG and SPEW) and the ability to differentiate between programmer debug messages and flash chip debug messages. Until the design for the message printing infrastructure is finished, this is the best stop-gap measure we can get.

I decided to fill in the info for a few chips to illustrate how this works both for uniform and non-uniform sector sizes. struct eraseblock{ int size; /* Eraseblock size */ int count; /* Number of contiguous blocks with that size */ }; struct eraseblock doesn't correspond with a single erase block, but with a group of contiguous erase blocks having the same size. Given a (top boot block) flash chip with the following weird, but real-life structure: top 16384 8192 8192 32768 65536 65536 65536 65536 65536 65536 65536 bottom we get the following encoding: {65536,7},{32768,1},{8192,2},{16384,1} Although the number of blocks is bigger than 4, the number of block groups is only 4. If you ever add some flash chips with more than 4 contiguous block groups, the definition will not fit into the 4-member array anymore and gcc will recognize that and error out. No undetected overflow possible. In that case, you simply increase array size a bit. For modern flash chips with uniform erase block size, you only need one array member anyway. Of course data types will need to be changed if you ever get flash chips with more than 2^30 erase blocks, but even with the lowest known erase granularity of 256 bytes, these flash chips will have to have a size of a quarter Terabyte. I'm pretty confident we won't see such big EEPROMs in the near future (or at least not attached in a way that makes flashrom usable). For SPI chips, we even have a guaranteed safety factor of 4096 over the maximum SPI chip size (which is 2^24). And if such a big flash chip has uniform erase block size, you could even split it among the 4 array members. If you change int count to unsigned int count, the storable size doubles. So with a split and a slight change of data type, the maximum ROM chip size is 2 Terabytes. Since many chips have multiple block erase functions where the eraseblock layout depends on the block erase function, this patch couples the block erase functions with their eraseblock layouts. struct block_eraser { struct eraseblock{ unsigned int size; /* Eraseblock size */ unsigned int count; /* Number of contiguous blocks with that size */ } eraseblocks[NUM_ERASEREGIONS]; int (*block_erase) (struct flashchip *flash, unsigned int blockaddr, unsigned int blocklen); } block_erasers[NUM_ERASEFUNCTIONS]; Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: https://code.coreboot.org/svn/flashrom/trunk@719 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
