rjo: Is there suppose to be a replacement for the fpga_program command in OpenOCD? Or does http://openocd.zylin.com/#/c/4090/ make sense

mithro: doesn't make sense to me. (a) there never was a fpga_program AFAICT (b) there are *_program() already (c) all your patch is doing is promote your functionally unrelated *_print_dna() function (d) it gets nasty for multiple TAPs.
<rjo>
mithro: but i would not reintroduce that just to make migen work again.
<rjo>
mithro: i renamed it because the code is device-dependent.
<mithro>
rjo: The idea was to provide a common command which works with any fpga (in the same way that the flash stuff works with any flash)
<rjo>
mithro: what you can do is add the fpga_program alias in the individual board .cfg there it doesn't collide.
<rjo>
mithro: you can't just put it into the device .cfgs because it breaks if you include multiple.
<rjo>
and you really don't need to mix unrelated functionality.
mumptai has joined #m-labs
stekern has quit [Ping timeout: 256 seconds]
<mithro>
rjo: that command is really more an FPGA reset?
mumptai has quit [Remote host closed the connection]
<rjo>
mithro: maybe. it does JPROGRAM, which is the same as pulsing PROGRAM_B. but let's not invent new terminology. and i'd assume that xilinx did not call that pin RST_B for a reason.
<rjo>
there are so many different "resets" around. resetting the TAP, resetting the target, resetting some clock domain...
<rjo>
mithro: if you want to play with openocd and jtagspi, there are two valuable items that i can see: 1) clean up and wire up the mor1kx debugging unit 2) implement one of the solutions in https://github.com/jordens/bscan_spi_bitstreams/issues/1
<mithro>
rjo: I do plan on wiring up the mor1kx debugging unit in the near future - but at the moment I'm just trying to get openocd to work with the arty (which it does) and using misoc/litex to flash the bitstream
