Re: New Lolin D32 Pro with 4MB PSRAM

So just a heads up for those considering this board. Ali-Express refunded my entire purchase price plus shipping for the two boards, never any technical response from Lolin. I did in my filing, link to this post sequence here on the Micropython forum, so Lolin would be able to duplicate just what I ...

Re: New Lolin D32 Pro with 4MB PSRAM

That's weird. Did you flash the official firmware or loboris port? If you flashed his port, you should ask on his forum as he is more likely to see the message there. Kevin, I flashed the Loboris port originally and got this boot loop behavior with several variants of the Loboris software loads. I ...

Kevin
The board does not 'work' in the sense that I cannot get to a REPL. On bootup after flashing the new binary, I enter a boot loop with:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x37 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371
ets Jun 8 2016 00:22:57

repeatedly.

Re: New Lolin D32 Pro with 4MB PSRAM

Has anyone successfully reloaded firmware into the new Lolin D32 Pro? Which firmware is compatible? I have tried a variety, they seem to load successfully with esptool, but then I keep getting the 'flash read error, 1000.'

Re: Preliminary pyboard port to NXP MCUs ---- how to add to micropython repository

Rocky I worked for a while with my colleague here, and we agree with stijn. He outlines a good path to bring your code into mainstream Micropython. From what we were able to tell, your Bitbucket original commit differed substantially from any versions of the main GitHub Micropython repository that w...
