The Data In-puts/Outputs output the data stored at the selected address during a Bus Read operation. Is this there an issue with 14.7 EDK? Query data are always presented on the lowest order data outputs. The sys-tem can read CFI information at the addresses given. ERASE commands are written to the command interface. address 55h in word mode (or address AAh in byte. Refer to the CFI Query instruc-tion to understand how the M36DR432 enters the. And if we only read low 8bit, we'll get the 0xff too. _SMSTSInWinPE. Can be used to test the RS232 setup. INTEL StrataFlash™ MEMORY TECHNOLOGY 32 … get the error: "No CFI table found at address " Probable Cause . The whole point in CFI is that you don't _need_ to have a specific reference to the chip in question. The standard Linux drivers should drive it just fine. To terminate reading CFI. It supports the following: • Read and Read Query, Automatic Write and Erase, Lock, and Status operations • 128-byte write page buffer and write/erase size • 16-byte page read buffer • 8-bit, 16-bit, and 32-bit operation Table 19.
