Hi.
I'm trying to flash bios to a motherboard MSI B450M-A PRO MAX.
I have connected to the "new type" JSPI1 connectors.
Think i have a connection to the chip, but its not listed on your chip list. Gets a response only once every time i power up the chip.
I use a CH341A PRO programmer with a 1.8V converter. Then connected wires directly to the motherboard. No unsoldering. Ubuntu 18.04.4 LTS

Can you help me?

Hi Nicklas,
well, at least you don´t have a good (enough) connection to the chip.
Check your log file: "probe_spi_rdid_generic:" should give you the same ID as given in the datasheet of your chip. Further it should give you always the same value. As the value changes a lot, it seems that you have bad cable connections or an signal integrity problem. Check the cables/cable connections and try with a lower frequency if the programmer supports this. Try with cables as short as possible as well.
Regards,
Simon
