Differences between the old and new versions of Chibios

blackberryer · Post by **blackberryer** » Thu Apr 17, 2025 4:17 pm

I just ported to the latest chibios version and have documented a lot of diffs, like the one below，I simply set the ‘_base_object_methods’ to 0, will there be a problem

Code: Select all

#define _base_sequential_stream_methods                                     \
  /* Stream write buffer method.*/                                          \
  size_t (*write)(void *instance, const uint8_t *bp, size_t n);             \
  /* Stream read buffer method.*/                                           \
  size_t (*read)(void *instance, uint8_t *bp, size_t n);                    \
  /* Channel put method, blocking.*/                                        \
  msg_t (*put)(void *instance, uint8_t b);                                  \
  /* Channel get method, blocking.*/                                        \
  msg_t (*get)(void *instance);                                             \

Code: Select all

#define _base_sequential_stream_methods                                     \

  /* Stream write buffer method.*/                                          \
  size_t (*write)(void *instance, const uint8_t *bp, size_t n);             \

  msg_t (*get)(void *instance);

Hi,

Not enough information, where do you have a problem with changes?

Because when I was porting F405, it took a lot of time, and I couldn't compile it properly;
So I switched to the new version of chibios, and finally it was successfully compiled, and the basic functions were implemented, but the I2S data was received incorrectly;
So I tried to test the new version of chibios with F303, and I2S also received unsuccessfully;

One thing that is certain: the F303 has fine I2S data on older versions of chibios;

So I'm comparing the differences between the old and new versions now to see if I can solve the problem of I2S data receiving errors

Or see if I can fix the F405 compilation error on older versions, here's the error I reported when compiling older versions

Code: Select all

ChibiOS/os/hal/src/hal_serial_usb.c: In function 'sduRequestsHook':
ChibiOS/os/hal/src/hal_serial_usb.c:323:19: error: request for member 'bmRequestType' in something not a structure or union

make: *** [ChibiOS/os/common/startup/ARMCMx/compilers/GCC/rules.mk:216: build/obj/hal_serial_usb.o] Error 1

Looking at the error it seems to be connected to USBv1 and the F405 should be using OTGv1，I'm confused by this error and don't know how to fix it

Hi,

The F4 uses OTGv1

Are you using custom build files? you should explain your setup or it is impossible to try to help.

Just now, I disabled USB, successfully compiled the old version, it runs successfully on F405, I2S data is fine，and i confirmed the compilation option, it's OTGv1

but I'm currently using the code of the old version of CHIBOS, I can't use OTGv1

One difference I see between the old and the new is USBDriver :

old version

Code: Select all

bool sduRequestsHook(USBDriver *usbp) {

  if ((usbp->setup.bmRequestType & USB_RTYPE_TYPE_MASK) == USB_RTYPE_TYPE_CLASS) {
    switch (usbp->setup.bRequest) {
    case CDC_GET_LINE_CODING:
      usbSetupTransfer(usbp, (uint8_t *)&linecoding, sizeof(linecoding), NULL);
      return true;
    case CDC_SET_LINE_CODING:
      usbSetupTransfer(usbp, (uint8_t *)&linecoding, sizeof(linecoding), NULL);
      return true;
    case CDC_SET_CONTROL_LINE_STATE:
      /* Nothing to do, there are no control lines.*/
      usbSetupTransfer(usbp, NULL, 0, NULL);
      return true;
    default:
      return false;
    }
  }
  return false;
}

lastet version

Code: Select all

bool sduRequestsHook(USBDriver *usbp) {

  if ((usbp->setup[0] & USB_RTYPE_TYPE_MASK) == USB_RTYPE_TYPE_CLASS) {
    switch (usbp->setup[1]) {
    case CDC_GET_LINE_CODING:
      usbSetupTransfer(usbp, (uint8_t *)&linecoding, sizeof(linecoding), NULL);
      return true;
    case CDC_SET_LINE_CODING:
      usbSetupTransfer(usbp, (uint8_t *)&linecoding, sizeof(linecoding), NULL);
      return true;
    case CDC_SET_CONTROL_LINE_STATE:
      /* Nothing to do, there are no control lines.*/
      usbSetupTransfer(usbp, NULL, 0, NULL);
      return true;
    default:
      return false;
    }
  }
  return false;
}

it's a lot of work to compare the differences between the whole version, so，just now I switched to a chibios version, and everything is still working fine at the moment, temporarily solving the problem

Hi,

You should align to newer versions, it is hard to keep track of all changes over the year, it can be done but it takes time.

I'm using an older version for the time being and migrating to the latest version once the issue is resolved

Now I notice that sdSetBaudrate is missing, what did it change to?

Hi,

It never had such a function, you are probably using some customized driver.
