Hi there,
i currently use the IS25LP128 flash chip with an LPC4370. The SPIFI interface is capable to run code in QuadMode directly from the flash chip. In order to activate the QuadMode you have to set a bit in the ISSI flash chip to signal that the FlashChip is able to run in quad mode.
Normally i had to set this bit just once because its non volatile. Currently with the newest JLink version this seems to be reset, when i flash a new program. So now i have to set the QE again every time i falsh the ISSI chip.
When i just disconnect the board from power and restart it, the quad mode stays enabled. So it seems that the software and the flash chip behave correctly.
Is this a new feature in the JLink software that also configuration bits in the FlashChip are reset when a new program is flashed ?
Thanks for the help.
Best,
Hans
