SPI NOR Flash support:
|
||||
======================
|
||||
|
||||
We can use an extern SPI NOR Flash with STM32F103-Minimum board. In this case
|
||||
we tested the Winboard W25Q32FV (32Mbit = 4MiB).
|
||||
|
||||
You can connect the W25Q32FV module in the STM32F103 Minimum board this way:
|
||||
connect PA5 (SPI1 CLK) to CLK; PA7 (SPI1 MOSI) to DI; PA6 (SPI MISO) to DO;
|
||||
PA4 to /CS; Also connect 3.3V to VCC and GND to GND.
|
||||
|
||||
You can start with default "stm32f103-minimum/nsh" configuration option and
|
||||
enable these options using "make menuconfig" :

|
||||

|
