Sylvain Munaut 98d8bee04f iceprog: Use open-drain output to drive SS and Reset line

Sylvain Munaut c5a8beffec iceprog: Improve reset to disable both CRM and QPI 
It's hard to cover 100% of cases, but this seems to improve
probability that a reset works, at least for me on the icebreaker.

Some other flash have a different QPI disable command though :/

Sylvain Munaut 502d847b41 iceprog: Add option that set QE=1 bit in SR2 
This is useful when testing litex SoC that rely on that bit being set

The setting is non-volatile so it only needs to be done once in case
you happen to have used a flash chip that's not by default QE=1

(This has been designed for winbond flash. Others might use
 different bit ...)

Piotr Esden-Tempski 24645e91a6 Added an option to choose the erase block size. 
This allows us to flash binaries at offsets that are smaller multiples.

iceprog: Better reset of flash
 2019-08-15 13:31:53 +02:00
Sylvain Munaut a7c42cd29b iceprog: Better reset of flash 
If the flash was in a 'weird' mode (like CRM, QPI, ...), sending
a continuous stream of 0xff should take it out of it.

It looks like the previous code was trying to do that, but
was only transferring 8 bits and then 2 bits which is way
too short.

Tim Pambor 26a40d0e11 Fix piping on windows 
On windows stdin and stdout have to be set to binary as otherwise windows treats it as text and converts occurences of CRLF to LF

Pablo Cossutta bd88dfe418 Add -X option to iceprog 
In my setup, in OSX I have problems reading from libftdi but not writing. In case of a failure iceprog exits and leaves the FPGA in an useless state. I think it would be a good option to have the possibility to skip the verification process.

Piotr Esden-Tempski 9a58588772 Slightly more robust flash wait function. 
In cases when the FLASH chip is bit flaky and the status register
"bounces" this flash_wait should be able to perform a bit better.

Also added more verbose output around block erase.
 2018-08-18 16:13:27 -07:00
Piotr Esden-Tempski 868ac2d93f Add a function to read and decode the status register. 
Very useful for debugging purposes. ;)

Piotr Esden-Tempski 20ef4efd8b Added the FTDI cable pinout for reference. 2018-08-18 15:29:11 -07:00
Piotr Esden-Tempski f4ff8f7630 Improved JEDEC ID read function. 
The function now checks how long the extended JEDEC ID field is for the
particular FLASH chip and only reads the amount provided by the chip.

Piotr Esden-Tempski 3ba1acf31b Replaced some more magic numbers with FLASH command IDs. 
I missed those the first time around.
 2018-08-18 14:46:12 -07:00
Piotr Esden-Tempski ee7eae0be8 Added easier to read chip_select/reset functions. 
Just calling a gpio function with two numbers was not very self
explanatory. The functions now refer to the actual indended action, chip
(de)select for flash, reset and chip (de)select for sram. Reading the
code and understanding what steps are taken should be easier now.

Piotr Esden-Tempski 96b1a90f28 Added more code comments. 
Main point was to group the code into three logical segments:
* MPSSE/FTDI defines and functions
* FLASH defines and functions
* iceprog implementation core

While I was at it I also added a few comments for stuff that was not
immediately obvious what it does.
