Hello,

I need support for read / write for IS25LQ016B-JNLE.
I try to connect in SQI mode, and here is the log:

FlashcatUSB Script Engine build: 225
SPI database loaded: 209 devices supported
Welcome to FlashcatUSB interfacing software, build: 370
Running on: Microsoft Windows XP Professional (32 bit)
Device connected in SPI mode, firmware version: 4,05
Successfully opened device in SPI mode (8 MHz)

Try this update and let us know then i will have a word with the developer if this does not allow you as to weather or not v1.x is compatible or not

Hello, I was tested. and it works!
But only work on standard SPI mode, not with SQI (Quad mode).
FYI using FCUSB.RC19.370 release is also success to read write in standard SPI mode.
for using (SQI) mode I see in the datasheet there is need write QE bit on Status register, similiar when using Winbond like W25Q16 in Quad mode.
Any chance to get it work in SQI mode?

Try and load the v2.x firmware for spi onto your v1.x board and see if that works , in the meantime i will get the developer to verify this as well

No not yet unfortunately .. but let me ask you a question or two first ...

Are you trying to read the XHRA-2HPA chip with fcusb ?
If so what does it show in console window ?
If it is this chip i am pretty sure it is not in the supported list at the moment .. still unsure if it can be added will ask the developer.

The XHRA-2HPA, is need to load firmware from IS25LQ016B, but only read in Quad mode.
So I need to write the firmware to IS25LQ016B in Quad mode and set the QE bit in status register so the XHRA-2HPA can read and load the firmware.
But untill now I just can read/write firmware on IS25LQ016B in Standard SPI mode.
I was probing the SIO2 and SIO3 pin on FlashcatUsb, there is no data transfer. just act like Standard SPI mode.

I believe you are using a self made board thus I will be unable to help you any further as it is not a genuine product from the developer , thus we cannot be sure your board is up to standard and could be wasting our time ...

Yes, like I say on email I build selfmade board (V1.x) series. I was explain that by email to developer, and they said the SQI mode can only work on V2.x board.
I will try to build the V2.x board and test again to connect in SQI mode.

Thank you
