OLS version used from: git://github.com/jawi/ols.git
|
||||
Warning sometimes there's a bug between Mode3 & Mode0 in OLS 0.9.6b3
|
||||
Expected is when /CS = 0 at first SCK Rising Edge data shall be read.
|
||||
|
||||
1) Read JDEC ID:
|
||||
----------------
|
||||
SPI Standard, Mode3, 8bits, MSB first, Show /CS & Honour /CS, SCK=About 32MHz:
|
||||
Send(MOSI)=0x9F(Read JDEC ID)
|
||||
Receive(MISO)=0xEF => Manufacturer ID(Winbond) and 0x40, 0x14 => Device ID
|
||||
|
||||
2) Read Status Register-2:
|
||||
--------------------------
|
||||
SPI Standard, Mode3, 8bits, MSB first, Show /CS & Honour /CS, SCK=About 32MHz:
|
||||
Send(MOSI)=0x35(Read Status Register-2)
|
||||
Receive(MISO)=0x02 (Status Register-2 => S15-S8)
|
||||
|
||||
3) Read Unknown Command 0xA3 (maybe for other SPIFI memory ??):
|
||||
---------------------------------------------------------------
|
||||
SPI Standard, Mode3, 8bits, MSB first, Show /CS & Honour /CS, SCK=About 32MHz:
|
||||
Send(MOSI)=0xA3
|
||||
Receive(MISO)=0x00 0x00 0x00
|
||||
|
||||
4) Fast Read Quad I/O with "Continuous Read Mode"(0xEB):
|
||||
--------------------------------------------------------
|
||||
SPI Standard, Mode3, 8bits, MSB first, Show /CS & Honour /CS, SCK=About 32MHz:
|
||||
Send(MOSI)=0xEB(Fast Read Quad I/O)

Nota:
|
||||
Tested on JellyBean.
|
||||
SCK is about 32MHz After about 620us from startup.
|
||||
SCK change to about 660KHz/700KHz during about 400us. (During Read from 00 0C 78 => During CGU SetPLL1 code).
|
||||
SCK change from 4MHz to about 8MHz during about 15us. (Read from 00 0D 98 => During CGU SetPLL1 code).
|
||||
SCK stabilize to 8MHz during 122us (no data anymore OLS memory is full) (Read from 00 05 B0).
|
||||
|
||||
...
|
||||
During Code running the SCK run at 8MHz MCU is configured at 72MHz => 12MHz(IRC)*6.
|
||||
SPIFI CLK(0x40050070) = 0xD000800 0x0D=IDIVB & 0x800=AUTOBLOCK_CLOCK_BIT Enabled
|
||||
IDIVB_CTRL(0x4005004C) = 0x9000820 => IDIB=1000(8+1)=9 => for 72MHz Core => 72/9=8MHz
|
||||
IDIVB_CTRL(0x4005004C) = 0x9000800 => IDIB=0000(0+1)=1 => for 72MHz Core => 72/1=72MHz => This configuration just crash.
|
||||
IDIVB_CTRL(0x4005004C) = 0x9000800 => IDIB=0000(0+1)=1 => for 72MHz Core => 72/2=36MHz => This configuration works fine.
