@nimaltd Hi, if you open any source file you can see

//////////////////////////////////////////////////////////////////////////////////////////////////////////
////////////// Please update the following configuration according to your Hardware spec /////////////////
//////////////////////////////////////////////////////////////////////////////////////////////////////////

The default pin assign only a template, update to what pins you are using then it should be OK

[nimaltd]

@wanckl Thanks for your answer. I did. But did not work

[wanckl]

@nimaltd Which pins you are using, I have tried just 1/2/3/4 is ok

[nimaltd]

@wanckl many different.
I can remember 0.1.6.7
But the same pin is working in master now.
I have 2 board wich are connectet.
C5 and C6
In one direction it can work.
C6 slave C5 master

[wanckl]

@nimaltd A bit confuse

So you are saying:

• both C5 and C6 is using 0/1/6/7
• pins is working fine on master with both direction
• C6 master and C5 slave is NOT working on v5.5 ?

right?

[nimaltd]

@wanckl yes.
But on c6 not sure. Maybe i used default pins.
But pining are correct. It is working in one direction.
C6 slave. C5 master

[wanckl]

@nimaltd Just tried priginal SPI slave hd seg_mode/append_mode example with both C5 and C5+C6 with following pins, on v5.5.3

#define PIN_NUM_MISO            0
#define PIN_NUM_MOSI            1
#define PIN_NUM_CLK             6
#define PIN_NUM_CS              7

But can't see any issue happens, can you provide more info like

• how you connect C5 and C6 (jump wire or custom board)?
• what means xxxx but cannot response?
• what the order you start master and slave

If possible it will mode accurate to provide the spi logic wave to see where issue is

[nimaltd]

@wanckl I am using header board.
Wroom c5 original board and another c6 header.
Also i tested with another c5 header board.
All pins connected by female to female wire . But wiring should be correct. Because when i use c5 as a master, it is working.
Not response, i mean when master send data to c5 slave, i cannot see the response by logic analyzer and on console.
I restarted both at the same time, one earlier, nothing changes.
Also I used a stm32 board as a master and c5 as slave, it did not work. I thought my stm32 code is not correct. Then i tried original esp idf example.
