Hello All, I have the following question.
After powering up Davinci chip, if NAND Flash is selected, RBL seems to send the two commands RESET/READID to NAND Flash Back to back. If NAND device has a READY/~BUSY pin, can the READID command be delayed by connecting the Ready/~Busy pin of NAND to EM_WAIT pin? My reason for asking is, I ran in some problems using the Micron MT29F2G08ABD (2 Gbit), After the RESET, NAND device goes busy (READY/~BUSY = 0) and takes longer to go Ready (READY/~BUSY = 1). The READID command is issued before the NAND becomes READY, and therefore the Manufacture/device IDs are not read correctly. The device has to be Ready before a READID command is issued. In turn, since the Device ID is not read correctly, booting from NAND fails. Regards, Naresh Naresh Kansara Irvine Sensors Corporation phone: (714)-435-8928 email: [email protected]
