h1. Flash chip by board h2. v1 boards n25q128 EPCQ128 compatible Read silicon id (0xab) gives 0xffffffff Read device id (0x9f) gives 0x20ba1810 (first 3 bytes count) Sector size 64KB (also supports 4KB) https://www.micron.com/~/media/documents/products/data-sheet/nor-flash/serial-nor/n25q/n25q_128_3_volt_with_boot_sector.pdf https://www.altera.com/en_US/pdfs/literature/hb/cfg/cfg_cf52012.pdf h2. v3 boards (aka v2) m25p128 EPCS128 compatible Read silicon id (0xab) gives 0xfffffff Read device id (0x9f) gives 0x20201800 (first 3 bytes count) Sector size 256KB https://www.micron.com/~/media/documents/products/data-sheet/nor-flash/serial-nor/m25p/m25p_128.pdf https://www.altera.com/en_US/pdfs/literature/hb/cfg/cyc_c51014.pdf h2. v3 2nd run boards (aka v2 FIX) S25FL127SABMFV000 EPCS128 compatible? Read silicon id (0xab) gives 0xffffff17 TODO Read device id (0x9f) gives 0x1220184d TODO (first 3 bytes count) Sector size? Seems to wipe core with 64KB, but seems to run well with 256KB? Need to check status register... Has some fancy hybrid sector 4K/64K thing. http://www.cypress.com/file/177961/download https://www.altera.com/en_US/pdfs/literature/hb/cfg/cyc_c51014.pdf
