How to boot qspi flash from GD flash(GD25q32CSIGR) on IMX6ULL board

Question asked by Lin allen on Jun 18, 2018
Latest reply on Jun 19, 2018 by Lin allen

My board is iMX6ULL

We can use the onboard QSPI NOR flash(micron-n25q256a) to boot up RTOS

And now we need to use another QSPI NOR flash(GD25q32CSIGR) to bringup the system

 

Have 3 config files for 3 NOR flash under MFG tool files

 

qspi-nor-macronix-mx25l51245g-config
qspi-nor-micron-n25q256a-config
qspi-nor-spansion-s25fl128s-config

 

I study LUT program sequence based on macronix-mx25l51245g

 

Please refer as follows: 

DATA                 |   INSTR   |  PADs  |  OPERAND  | ---------------------------------------------------------------------------------- 0x08 => 000010 00    |    10     |   0    |           | >> ADDR, PAD0, 24 bit 0x18                 |           |        |   0x18    | ---------------------------------------------------------------------------------- 0x04 => 000001 00    |    1      |   0    |           | >> CMD, PAD0, 0x3B 0x0B                 |           |        |   0x0B    | ---------------------------------------------------------------------------------- 0x1C => 000111 00    |    7      |   0    |           | >> READ, PAD0, 0x04 0x04                 |           |        |   0x04    | ---------------------------------------------------------------------------------- 0x0C => 000011 00    |    3      |   0    |           | >> DUMMY, PAD0, 0x08 0x08                 |           |        |   0x08    | ---------------------------------------------------------------------------------- 0x00 => 000000 00    |    0      |   0    |           | >> STOP, PAD0, 0x00 0x00                 |           |        |   0x00    | ---------------------------------------------------------------------------------- 0x24 => 001001 00    |    9      |   0    |           | >> JMP_ON_CS, PAD0, 0x00 0x00                 |           |        |   0x00    | ----------------------------------------------------------------------------------

Now I trying to use LUT program sequence of macronix-mx25l51245g to boot up GD flash (GD25q32CSIGR)

Because of the GD25q32CSIGR sequence is same with macronix-mx25l51245g
