Current TD 4.6.4 license was valid until 02/08/2020. Right now I got License expired error.
Please upload new license file to https://dl.sipeed.com/

Please document which camera and LCD modules were used for testing this demo. That would help people get started more quickly using the FPGA board.

Is there a touch sense LCD that works with this board?

Thanks!

Is possible to increase ram to 400KB? i love mruby but it needed more ram.

The comments in the top part of this file are garbled (on a non-Chinese computer). Other files are OK, for example I can see Chinese text in lcd_sync.v.

lcd_sync.v中，vsync_cnt赋值错误：
assign vsync_cnt = counter_hs;
应该为
assign vsync_cnt = counter_vs;
由于编码方式设置的不同，我没有发起pr，那样看起来像是每一行都改动过了。

Hello,

I think I bricked my GD32. It does not boot and when I read from the flash it reads 'FFFF...'. Any solution to this? Where can I find replacement chip with QFN package?

Hello. I got an error.
Here is the console output:
CMD-004 : start command "optimize_rtl"
RUN-001 : Open license file D:/Anlogic/TD4.2.511/license/Anlogic.lic
RUN-003 ERROR: License expired!

Where could I get the license file? Reinstalling did not help.

Does register initial value work?

Verilog example:
reg [7:0] variable = 56;

No errors but looks like initial value is "0".

There is a new version of the IDE (TD_RELEASE_March2022_r5.5.1_47752) available on the Anlogic website (https://www.anlogic.com/support/tools-downloads) but needs a login and that is not really doable for outside China users.

It would be nice if this new version was made available here or on the Sipeed download space.

R3 -> High
J14 -> Low
P13 -> High
Expectation: Green lights.
Observation: Blue lights.

R3 -> High
J14 -> High
P13 -> Low
Expectation: Blue lights.
Observation: Green lights.

Hypothesis: RGB led G and B pins are swapped.

Just downloaded the most recent Tang Dynasty version (4.6.6),
unfortunately the Anlogic_202003.lic is expired.

How can I continue development?

Thanks & Regards,
Hagen
