can't open device #8

Closed tomaszduda23 closed 3 years ago

tomaszduda23 commented 3 years ago

For some reason it does not work with mainline driver. After getting pcan driver it is detected correctly but works only sometime. After building pcan driver with #define DEBUG_TRACE and DBG=DEBUG works every single time. It also does not work on win32. Any clue?

@tomaszduda23

It also does not work on win32. Any clue?

It works perfect for me under Linux and Windows, maybe you can provide more information ? Did you build firmware yourself or you try precompiled binaries ? I recommends to use precompiled binaries first.

*update: Please check schematic of your motherboard for pin coflicts, as example:

PB9 CAN1 TX and also CS43L22 SDA pin on your dev board. PB6 also shared with CS43L22

it can provide conflict with hardware CAN module and firmware will never run properly.

tomaszduda23 commented 3 years ago

I built myself first. Now I just tried precompiled pcan_pro_hw_2021_06_11.hex it still does not work. Which driver do you use on linux?

I noticed that after connecting device first command seems to be ok. Than each next command fails:

Maybe it is issue with my hardware itself? Strange thing is that it works randomly. I can provide more information if you need.

please check updated information about pin conflicts what i provided, but it works for any Linux distro i use, Ubuntu 18.04, Ubuntu 21.04, Windows 7 x86, Windows 10 x64 and not only for me. i think this is hardware issue

moonglow commented 3 years ago

Another thing, you can't pins left open and connected to audiochip, i think I'm sure what this is main problem because i have a lot of users ( i also use it myself ) has no problem. You can't left CAN pins open because it will never get IDLE state while configuration, so what i will do in your situation, first of all you need to resolve all pin conflicts and you need also add CAN phy or if you haven't you need to add something like that to CAN init pins:

#define CAN1_RX  B, 8, MODE_AF_OD, PULLUP, SPEED_FREQ_VERY_HIGH, AF9_CAN1
#define CAN1_TX  B, 9, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN1

#define CAN2_RX  B, 5, MODE_AF_OD, PULLUP, SPEED_FREQ_VERY_HIGH, AF9_CAN2
#define CAN2_TX  B, 6, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN2

Another solution it is remove all CAN related function ) and you will get just working USB stub without actual CAN functionality

I'm using SN65HVD230D (CAN2). As long as CAN side is "floating" it always crash like bellow. It also crashes in the car.

moonglow commented 3 years ago

it always crash like bellow. return HAL_ERROR; < - this one fails during pcan_can_init_ex

because CAN periphery can't get idle state, whats why i recommends before to configure it as AF_OD with PULLUP useful if you have board without CAN transceivers. If CAN periphery can't be init it goes to assert( 0 ) construction, because it is fatal error.

About this:

#define CAN2_RX B, 5, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN2
#define CAN2_TX B, 7, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN2

#define CAN1_RX B, 8, MODE_AF_OD, PULLUP, SPEED_FREQ_VERY_HIGH, AF9_CAN1
#define CAN1_TX B, 11, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN1

You can't use CAN peripheral with any pins you want. As example in your case ( according to device datasheet, Table 7 ) :

PB5 - has alternate function as CAN2_RX PB7 - does not have alternate function for CAN periphery. PB8 - has alternate function as CAN1_RX PB11 - does not have alternate function for CAN periphery.

So... i think this is your main problem you can try this TEST firmware without CAN pins used ( i just make it virtual ), just to check if you solder your USB pins correct, if it will works for you, next step you will need to sure what pinout is correct and i think all be OK.

tomaszduda23 commented 3 years ago

You are right. I forgot about alternate functions table. Bellow works correctly.

#define CAN1_RX B, 8, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN1 #define CAN1_TX D, 1, MODE_AF_PP, NOPULL, SPEED_FREQ_VERY_HIGH, AF9_CAN1
