ISP_DFU_20 driver transfer file in case of USB 2.0 (NUVOTON M487KM) driver development

[SANKETMODHE7028]

some issues happen in data transmission .

1 . i have to transmit or receiving the data . so how to do this?
2. i have to change in DFU_Transfer file ?
3. void HSUSBD_ProcessSetupPacket(void)
{
/* Setup packet process */
gUsbCmd.bmRequestType = (uint8_t)(HSUSBD->SETUP1_0 & 0xfful);
gUsbCmd.bRequest = (uint8_t)((HSUSBD->SETUP1_0 >> 8) & 0xfful);
gUsbCmd.wValue = (uint16_t)HSUSBD->SETUP3_2;
gUsbCmd.wIndex = (uint16_t)HSUSBD->SETUP5_4;
gUsbCmd.wLength = (uint16_t)HSUSBD->SETUP7_6;

/* USB device request in setup packet: offset 0, D[6..5]: 0=Standard, 1=Class, 2=Vendor, 3=Reserved */
switch(gUsbCmd.bmRequestType & 0x60ul)
{
case REQ_STANDARD:
{

    HSUSBD_StandardRequest();
    break;
}

case REQ_CLASS:
{
    DFU_ClassRequest();
    break;
}

4.In hsusbd_user.c file only HSUSBD_StandardRequest() function is working for configuration part . when DFU_ClassRequest() ; function is called?
5. suppose i have to pass data so I have to calling seperately?
6. please give me the proper logic.

for example : - I have to transmit arr[10] = {1,2,3,4,5,6,7,8,9,0}; how to transmit ?
control in or control out.

case:

pc utility <--------------------------------> device
TX
command 9 ----------------------> 1st byte received.
RX
2 received <------------------------ 2 (device sending 2)
ACK
6 -------------------------> ACK byte received

64 bytes received < -------------------------- 64 bytes data packet send to pc

note :- 9 and 6 are random value of 1 bytes.

this is the flow of code so please find a perfect logic for this .

I'm not quite clear on your point of concern. You don't need to trace the driver unless you want to write a separate driver yourself. Using this sample, please refer to the documentation under the WindowsTool directory.

ok ........
only give me idea when the DFU_CLASS_REQUEST function is called?
and how to buffer read or write?

[ychuang3]

DFU_ClassRequest() is called when DFU class command received from USB Host (Windows PC).
Data is from USB Host and directly programmed to flash., refer to the WriteData().

Could you explain the purpose of wanting to trace the code? Thank you.

ok.....
suppose i have to transmit this buffer having some data buff[10] = {1,2,3,4,5,6,6,7,8} . how to send this device to pc?
can i used directly controll_ in() function ?

[ychuang3]

The USB device is passive, and all data transmission is initiated by the USB Host. Therefore, you must perform read operations from the Windows PC side for the USB device to receive commands and carry out corresponding data transfers. We do not provide the source code for the Windows side; this sample is intended for firmware updates. What is the purpose of sending data to the PC side? There may be other suitable sample codes, but since you haven't clearly explained your purpose, I'm unable to provide specific helpful suggestions.

I am not getting properly concept. do you have any proper datasheet on DFU ?
and how to handle this please explain first..

actually i am working on project so my task is to transmit or receive the data . using DFU_transfer file .

You can find DFU spec. by Google search...

Looks like your project is not on Nuvoton M480 platform, right?
I think you don't even run the sample code.

[SANKETMODHE7028]

controller is NUVOTON M487KM .

actually totally working in background only HSUSBD_StandardRequest(); this function run for configuration part.

only this is showing in usb analyser

i searched this but how to use in my project?

The link to USB org including DFU spec.
https://www.usb.org/documents?search=&type%5B0%5D=55&items_per_page=50

Please find:

HSUSBD_StandardRequest() is for standard request, that is, for any USB device. DFU data transfer use class commands, not standard commands.

Do you run the ISP tool or any program supports DFU on the host PC?

I have Numicro ICP programing tool utility .
and in my project EL series utility are used . for that host (pc) sending first command to slave (device)..
so how to use this class command?

i am using this DFU file and discriptor file . only changed in VID and PID for HMI detection . remaining code is same . so what i do first step?

[ychuang3]

Not ICP tool, please use ISP tool which is for ISP_XXX samples.
