LPCScrypt spifi w/LPC54608

Hi All,

I'm testing an OM13092 LPC54608 eva board.

MUXpresso IDE debug runs fine but I'm facing issues with LPCScrypt MT25QL128 Quad-SPI flash support:

after booting LPCScrypt with

./boot_lpcscrypt

lpcscrypt queryspifi command shows no spi flash available.

Jumper are at default state and lpcxpresso54608_driver_examples_spifi_polling_transfer project works correctly.

Am I missing something to support direct SPIFI flash support within LPCScrypt?

Thanks in advance,

Enrico

According to the LPCScrypt home page:

LPCScrypt is a command-line based, fast flash, EEPROM, OTP and security programming tool for LPC1800 and LPC4300 series microcontrollers.

No mention of LPC54xxx parts.

I suspect that you have connected to the on-board debug adapter (which is based on LPC43xx) and not (as you expected) the LPC54xxx.

Yes, I'm connecting to the on-board probe, so I guess the queryspi command refers to any external memory directly connected to the LPC4300 (while on the OM13092 board the external memory is connected to the LPC54608).

So I guess the LPC SPI bridge can only be used within MCUXpresso IDE and not with LPCScrypt tool.
