SST26 not working with STM32F429ZI

Hi, I am running the SPIMemory V.3.4.0 library with a NUCLEO-F429ZI board and the SST26VF032 memory chip the sketch is extracted from an example.
I tried to include the SPIMemory library and it doesn't work, only with SPIFlash it works
I checked what my deault SPI is and made the following connections:
NSS: PA4 -> CE # (1)
SCK: PA5 -> SCK (6)
MISO: PA6 -> SO / SIO1 (2)
MOSI: PB5 -> SI / SIO0 (5)
VCC -> WP # / SIO2 (3), HOLD / SIO3 (7), VDD (8)
GND -> VSS (4)
The output of my serial is
16: 34: 06.650 -> Get JEDEC ID
16: 34: 06.650 -> Manufacturer ID: feh
16: 34: 06.650 -> Memory Type: feh
16: 34: 06.650 -> Capacity: feh
16: 34: 06.650 -> JEDEC ID: fefefeh
Sketch:
#include<SPIFlash.h>
HardwareSerial Serial1(PD9, PD8);
char printBuffer[128];
SPIFlash flash(PA4);
void setup() {
Serial1.begin(115200);
Serial1.println("####\nStart setup!" );
delay(50);
flash.begin(MB(32));
Serial1.println("End setup!\n####");
}
void loop() {
Serial1.println(F("----------------------------------------------------------------------------------------------------------------------------------"));
Serial1.println("Get JEDEC ID");
uint8_t b1, b2, b3;
uint32_t JEDEC = flash.getJEDECID();
//uint16_t ManID = flash.getManID();
b1 = (JEDEC >> 16);
b2 = (JEDEC >> 8);
b3 = (JEDEC >> 0);
clearprintBuffer();
sprintf(printBuffer, "Manufacturer ID: %02xh\nMemory Type: %02xh\nCapacity: %02xh", b1, b2, b3);
Serial1.println(printBuffer);
clearprintBuffer();
sprintf(printBuffer, "JEDEC ID: %04xh", JEDEC);
Serial1.println(printBuffer);
Serial1.println(F("----------------------------------------------------------------------------------------------------------------------------------"));
delay(5000);
}
void clearprintBuffer()
{
for (uint8_t i = 0; i < 128; i++) {
printBuffer[i] = 0;
}
}
Why do I always get that strange string "feh" and "fefefeh"?
