[OOB 5.10] Fails to write/read on DISCO_L475VG_IOT01A #15

Closed maclobdell closed 4 years ago

maclobdell commented 6 years ago

To test the quad spi driver, I created an example application and pushed it here: https://github.com/maclobdell/mbed-os-example-quadspi-mpl (master branch).

It uses the latest qspif-blockdevice (#5f9ffe...) and the code snippet at readme on the qspif driver repo.

Compiler Tested: ARM compiler 5. Platform Tested: DISCO_L475VG_IOT01A

When I download and run it, I expect to see "Hello World!" on the terminal.

But, it never shows Hello World.

QSPI SFDP Flash Block Device example
QSPIF BD size: 8388608
QSPIF BD read size: 1
QSPIF BD program size: 1
QSPIF BD erase size (at address 0): 4096

Does this indicate that it failed to write or read the Quad SPI flash?

Response to Read Manufacturer ID on DISCO_L475VG_IOT01A is "[DBG ][QSPIF]: Vendor device ID = 0xc2 0x28 0x17 0x0"

https://github.com/ARMmbed/qspif-blockdevice/blob/master/QSPIFBlockDevice.cpp#L195

Is this switch applicable for this ST device as well?
