    Yes, see https://github.com/openshwprojects/OpenBK7231T_App/issues/1769

    Added after 1 [hours] 42 [minutes]:

    3.0.78 builds
    https://github.com/NonPIayerCharacter/OpenBK7231T_App/actions/runs/17167633393
    Used BK7231N wpa supplicant for BK7231U/T and BK7252.
    BK7231T works with it.
    Last release - 510kb. This one - 497kb
    Removed wolfssl dependency from original libs with ar -d
    Size increased by 1792 bytes, but there would be no hidden surprises that way.
    A bug i've seen - on every seconds timer triggered several times instantly during OTA

    @divadiow
    There is a 'bug' in your beken_freertos_sdk_release repo.
    Since you probably just unpacked newer version on top of the older one (like i did for mine), some files that were deleted/moved remained.
    I've had build error with BK7252, because audio_pub.h was in two folders at once, and older version was included.
    Older: https://github.com/divadiow/beken_freertos_sd...blob/3.0.78/beken378/driver/audio/audio_pub.h
    Latest: https://github.com/divadiow/beken_freertos_sd...ob/3.0.78/beken378/driver/include/audio_pub.h

    damn yes. I was after a nice way to see the differences between versions but actually the correct way would have been to delete the lot between branches? Hmm.

    Anyway, anything caught your interest in .78 vs .76?

    It became possible to use mbedtls exclusively (without wolfssl) on BK7231U/T and BK7252.
    That reduced binary size significantly.
    Plus an idea came to me to play with mbedtls config. I removed some unneeded things to cut binary size.
    Plus i tried mbedtls 2.27.0 (default is 2.6.0). Binary size was increased some, but there were more free heap, + there were more idle cycles (?) (from 140-150k to ~170k).

    Great! @insmod , a question - I didn't do SSL on LWIP on any of the platforms yet, so far I only used HTTPS on ESP, but now I am wondering... would it be possible to move SSL to shared app, like you did with mqtt.c? I don't know currently how SSL is done under the hood, but isn't it just relying on LWIP raw TCP sockets, nothing more? Wouldn't it be possible to have SSL added to obk shared app once and have it working for all platforms (if enabled)?
    Helpful post? Buy me a coffee.

    I would rather want to have more streamlined solution for enabling SSL for MQTT (that was in PR for Beken and supposedly works, but is disabled) and for HTTP (sendGet/SendPost). If possible, in obk_config.h, but then we would need to inject it in LWIP? So probably no obk_config, but a build switch at compile time.

    With HTTPS enabled, we could try to fetch OTA files directly from Github (instead of asking user to download it and drag and drop).

    Of course, HTTPS would be disabled by default - just leave it as an option

    3.0.78 ready?
    Disabled many unnecessary features in mbedtls.
    RBL sizes:
    BK7231T_ALT - 1.18.158 522736 | 1775_merge_ae487f10134d 496224
    BK7231N_ALT - 1.18.158 511120 | 1775_merge_ae487f10134d 492528
    BK7238 - 1.18.158 510592 | 1775_merge_ae487f10134d 498752

    BK7231T_ALT is 26512 bytes lighter
    BK7231N_ALT is 18592 bytes lighter
    BK7238 is 11840 bytes lighter

    + used mbedtls 2.27, instead of 2.6.
    This resulted in a speed increase? (by 5-10k idle cycles on BK7238) and 2k less free heap compared to last release (most likely the result of disabling MBEDTLS_AES_ROM_TABLES to save flash size).

    Were there irRemoteESP tests done with https://github.com/openshwprojects/OpenBK7231T_App/pull/1771 ?

    I have only seen BK7231N boot from QIO flash and tested BK7238 UART/TuyaMCU with 3.0.78

    is there anything specific you need to know or just that it boots on all BK covered by this SDK?

    Well, it boots for me on T and 7238.
    So other most likely work as well.
    Plus there are new bootloaders for 7231U/7252/7238.
    But they probably work fine too.

    on the BL for BK7252U, do you know why it seems i have to splice in older test BL for the Tuya BK7252U flavour to boot?

    Tuya BK7252 QIO is fixed, i believe.
    Bootloader was first encrypted, then added default partition table on top of it.

    Added after 1 [hours] 17 [minutes]:

    Well, it turns out sendPin in myIRsend was never set to anything.

    Added after 10 [minutes]:

    Fix uploaded, logic analyzer shows that behaviour is the same as in 1.18.153.
    I also disabled https://github.com/openshwprojects/OpenBK7231...015edf449a6d048d028b1a0f/src/new_pins.c#L2155
    No effect on PWM for me.

    Added after 1 [hours] 24 [minutes]:

    IRSend NEC-1-18-1
    On RTL87X0C, it looks very similar to BK7238 in logic analyzer.
    Except on BK7238 frequency is shown to be 38.1 kHz, and on RTL87X0C it is 38.46 kHz.
    And some delays are different.
    In ESPHome that command is decoded into "Received NEC: address=0xFE01, command=0xE718 command_repeats=1".
    So, IRSend is now working on Realteks.

    Added after 8 [minutes]:

    I don't know if IRRecv works properly on RTL87X0C, but it somewhat recognizes my air conditioner (it shows ELECTRA_AC, same as in tasmota).

    Added after 3 [minutes]:

    And it really works on RTL87X0C.

    irRemoteESP fix can be merged (https://github.com/openshwprojects/OpenBK7231T_App/pull/1771)
    BK7238 works ok
    RTL87X0C works ok (both recv and send)
    RTL8720D doesn't work (send pwm is always on, recv doesn't work for me.)
    RTL8721DA doesn't work (send delays are too long, recv unknown, but consistent).

    Disabling PWM update in PIN_ticks has no effect on smooth led transition (flag 18). Continues to work as before.

    BL602 irRemoteESP build: https://github.com/NonPIayerCharacter/OpenBK7231T_App/actions/runs/17257858816
    send works for me.
    receive - in this build it doesn't, but if i disable pull up here (set it to false), then it starts working for me.

    I saw report that this irRemote issue is fixed, what was wrong? Looks like... you're culling repetitive calls to PWM?

    Now second call to HAL_PIN_PWM_Start will get culled... interestingly enough, you set g_periods[pwmIndex] before culling?

    The issue was that sendPin in myIRsend was never set. So HAL calls did nothing.

    That's this fix:
    Source code diff showing changes to myIRsend class function in a C++ file.
    So what is the purpose of g_pwm_on?

    So that pwm is not reinitialized on every enableIROut call.
    It wasn't before moving to HALs.
    Plus it simplifies setting g_periods[pwmIndex], compared to what was before.

    But with this:
    Code: C / C++
    Log in, to see the code

    This will ignore period change on repeated init start.... however I'm not sure if it affects anything.

    I'll merge it for now, just curious.

    Doesn't affect anything, since period is used HAL_PIN_PWM_Update.

    Ok, acceptable, let me know if there are any more PRs to merge.

    Regarding BK7238 - I will probably try testing it soon with multiple WS2812 clones, I have some similar strips that may have different timings.

Topic summary

The discussion centers on the NiceMCU XH-WB3S development board featuring the BK7238 SoC, initially suspected to be BK7231T but confirmed as BK7238. Users share experiences with flashing, testing, and porting firmware, including challenges with encryption keys, flash IDs, and bootloader compatibility. The BK7238 uses 2MB flash with varying encryption keys per chip, complicating universal firmware flashing. Tools like BKFIL and Easy Flasher (EF) are used for backup and restore, with EF supporting full flash erase and restore including bootloader. Flash ID support was extended to include missing flash chips to avoid CRC errors. Arduino SDK and Beken FreeRTOS SDK (version 3.0.70.1 and newer 3.0.76) are referenced for development, with partial support for BK7238 and related chips (BK7231N, BK7231U, BK7252). Porting efforts include adapting delay functions for 160MHz BK7238, resolving flashvars alignment issues due to 64-bit time_t, and addressing HTTP server and TCP socket stability problems in LWIP. OTA updates are functional but require correct image types and bootloader versions. Power save modes and their impact on peripherals like BL0937 energy meter and DS18B20 sensors are discussed, with some instability noted under power save. SPI flashing and UART flashing methods are compared, with SPI preferred for some devices. BK7231U (CC8000 chip) support is emerging, with builds available but some undefined references and boot issues. BK7252 camera module support is experimental, with encrypted flash complicating firmware use. Users report issues with DS18B20 sensor timing on BK7238 due to delay_us inaccuracies, partially fixed by new SDK delay implementations. Logging and MQTT load affect system stability and sensor reading consistency. The community shares flash dumps, toolchain links, and SDK forks to aid development and testing. Overall, the thread provides detailed technical insights into BK7238-based NiceMCU boards' flashing, SDK porting, peripheral support, and firmware development challenges and progress.
