10:38 <schoutem> Hi everybody; I'm looking at openFPGALoader to program a Spansion S25FL128L configuration flash which is connected to Xilinx xc7a50tfgg484 and to be programmed from a x86 host running debian using digilent_hs3. I have the setup all set and built. I made a modif to the board.hpp for the type of SPI Flash (data taken from datasheet). The connection

10:38 <schoutem> is fine and FPGA and Flash are detected; but I get a timeout when the erasing phase starts. Am I here in the right place to ask for some help with this?

11:15 <trabucayre> schoutem: hi

11:16 <trabucayre> is it a custom board ?

11:16 <trabucayre> board.hpp must be updated if your board isn't already supported, and spiFlashdb.hpp for your chip

11:17 <trabucayre> could you pastebin openFPGALoader logs ?

11:21 <schoutem> Hi, it's a custom board; but I believe I'm supplying all the parameters on the command line.

11:23 <trabucayre> nothing more ?

11:27 <schoutem> no, well, it keeps sending erasing.. messages but each time times out

11:27 <schoutem> I added this section for the SPI FLash :

11:27 <schoutem>  {0x016018, {

11:27 <schoutem>   .manufacturer = "spansion",

11:27 <schoutem>   .model = "S25FL128L",

11:27 <schoutem>   .nr_sector = 256,

11:27 <schoutem>   .sector_erase = true,

11:27 <schoutem>   .subsector_erase = false,

11:27 <schoutem>   .has_extended = true,

11:28 <schoutem>   .tb_otp = false,

11:28 <schoutem>   .tb_offset = (1 << 5),

11:28 <schoutem>   .tb_register = STATR,

11:28 <schoutem>   .bp_len = 3,

11:28 <schoutem>   .bp_offset = {(1 << 2), (1 << 3), (1 << 4), 0}}

11:28 <schoutem>  },

11:29 <schoutem> Can I paste the screenshot of STAT1 register table in image form here?

11:36 <trabucayre> better way to cpy/paste is to use pastebin. For picture I don't know

11:38 <schoutem> sorry for that; I'm not sure how to pastebin

11:40 <trabucayre> https://pastebin.com/

11:57 <trabucayre> or simply open an issue :)

11:59 <schoutem> ok!
