examples/wifi are not working on Sipeed M0S Dock BL616

[bvernoux]

examples/wifi are not working tested on Sipeed M0S Dock BL616 How to reproduce:

• Use https://github.com/bouffalolab/bouffalo_sdk/tree/master/examples/wifi/sta/wifi_http
• Build it with the toolchain and flash it (using bootloader)
  • Toolchain tested https://github.com/bouffalolab/toolchain_gcc_t-head_windows & https://github.com/bouffalolab/toolchain_gcc_t-head_linux
  • cd "path/examples/wifi/sta/wifi_http"
  • make ninja CHIP=bl616 BOARD=bl616dk
  • Enter Bootloader (keep BOOT pressed and connect USB-C to PC)
  • make flash CHIP=bl616 COMX=COMPort
  • All is ok (no error returned and flash is done with success)
• When connecting to the shell over UART (with an FTDI C232HM DDHSL-0 connected at 2MBauds) the shell is not working and everything seems frozen.
  • It is expected to have the shell access to enter the command to connect to the AP to test WIFI ... (like in example wifi_sta_connect BL_TEST 12345678 ...)

For information on same board (Sipeed M0S Dock BL616) other examples like examples/shell/shell_os (which is used in wifi examples), examples\peripherals\usbdev\usbd_msc_ram...work perfectly with an FTDI C232HM DDHSL-0 used for Serial Port (2Mbauds by default) for logs/shell...

M0s has no psram, so it fails.

M0s has no psram, so it fails.

Does there is a way to avoid using psram for WIFI example ? (especially to be compatible with Sipeed M0S Dock BL616...) It will be great to have basic example which does not use psram (I doubt we need more than 500KB for that else there is clearly an issue)

modify proj.conf, disable CONFIG_PSRAM

[sakumisue]

Please wait for sta_connect done.

[bvernoux]

Thanks the hint to disable CONFIG_PSRAM (CONFIG_PSRAM 0) in proj.conf work fine now the console is working

Tested with https://github.com/bouffalolab/bouffalo_sdk/tree/master/examples/wifi/sta/wifi_http (My router is not BL_TEST but it is the same on the real one) wifi_sta_connect seems to fail (like anything related to wifi) see logs:

bouffalolab />wifi_sta_connect BL_TEST 12345678
bouffalolab />wifi_http_test www.free.fr
bouffalolab />Http client task start ...
file [D:/_proj/__Lab_Tools/RISCV/Bouffalo_Lab_Dev/bl_mcu_sdk/components/os/freertos/queue.c]
func [xQueueSemaphoreTake]
line [1507]
( pxQueue )
vAssertCalled

Also wifi_scan fail (even if I reboot the board and I do only that command)

bouffalolab />wifi_scan
bouffalolab />Run WifiMgmr init first...
scan failed

WIFI does not start, so why do you input cmd?

[bvernoux]

Forget about my previous log I had disabled the wifi code to check the console works (and it was not working because of CONFIG_PSRAM 1) and I have forgotten to reenable it I have reverted my change to the code and the WIFI work fine now thanks for all My advise will be to change the CONFIG_PSRAM (CONFIG_PSRAM 0) in proj.conf for all examples to be compatible with basic dev board without PSRAM with BL616 like the Sipeed M0S Dock BL616

[sakumisue]

Thanks, i will modify.

[sakumisue]

done.
