# This phone has 3 memory chip selects: # # nCS0: flash chip select 1 # nCS1: RAM chip select # nCS3: flash chip select 2 # # All 3 chip select lines go to the same physical IC, a RAM/flash MCP. # We set WS=4 for all 3 here, copying what OsmocomBB does. The access # time listed in the datasheet is 70 ns for both RAM and flash, and per # my math setting WS=3 *might* work, but it could be marginal, so let's # play it safe for now. w16 fffffb00 00A4 w16 fffffb02 00A4 w16 fffffb06 00A4 # We also need to switch the CS4/ADD22 pin from its default function # of CS4 to the needed ADD22. w16 fffef006 0008 # With this phone all Calypso serial access always goes through the # CP2102 usb2serial IC inside the phone itself, which is programmed # to support the high non-standard baud rates. So we can safely # switch to 812500 baud unconditionally. baud 812500
