Is there any way to force JFlashSPI to write a custom SPI command *before* it tries to read the flash ID? I'm using a JLink Plus to program a W25X40CL SPI flash[0] for a Lattice ICE40 FPGA. The FPGA reads the configuration bitstream from the flash at reset, and then issues the 0xB9 (Deep Power Down) command to the flash chip[1]. After that command, the flash chip does not respond to any commands except for 0xAB (Release from Deep Power Down). When the JFlashSPI tries to read the flash ID (0x9F),…
