we are seeing that memory region from 0x16FFFF to 0x17FFFF not erasble, not seeing with old chips
hello, the softune workbench it can´t debug the software and sends this message " FR family softune workbench has stopped working" Help please
Show LessCurrenly I am evaluate a automative project. I am interested in crypress Traveo Graphic Soc S6J326Cx and S6J328Cx which have 3d graphic core. I have the following questions:
1, The ability of the 3D graphic core?
2, Does the 3D graphic core support opengl ES/opencl?
3, What is the requirement of operating OS if integrating 3D graphic core?
4, Can 3D graphic driver/lib support bare-metal sw development environment?
5, If use Cypress 3D graphic chip, which graphic related software will provide?
If possible, can someone provide <<3D Graphics Core Programmers REFERENCE manual>>.
Show LessHello ,
I am modifying the ethernet example , but doesn't work .
perhaps there is a working example .
while (1)
{
if ( 0 != EmacGetFrameLength(&EMAC0) ) // Emac received data?
{
LwIPInputHandle(); // Lwip handle the received data
}
LwipPeriodHandle(); // Lwip clears ARP table every 5 second
if ( 0 != EmacGetFrameLength(&EMAC0) ) // Emac received data?
{
err = udp_bind(upcb, IP_ADDR_ANY, UDP_SERVER_PORT);
IP4_ADDR(&ip6,192,168,7,11);
pb = pbuf_alloc(PBUF_TRANSPORT, 512, PBUF_REF);
pb->payload = str;
pb->len = pb->tot_len = 512;
udp_connect(upcb, &ip6,5000);
udp_send(upcb, pb );
udp_disconnect(upcb);
pbuf_free( pb);
}
}
I would appreciate any comment.
I have several questions related to programming the nonvolatile Flash memory on Cypress S6J32GEKSNEE2000
1) What is the expected/max current draw on the device? Datasheet 002-10689 Rev *J states that VCC12 draw 1250 mA during operation, but could that be less when just programming the device?
2) I have found instructions for Serial Programming in Chapter 14 of S6J3200 Series Hardware Manual Doc. No. 002-04852 Rev. *F. Is this the only method of programming the NVM, and if so is there an example bootloader project for this device?
2a) What frequency crystal should be connected between X0 and X1?
3) Is there an evaluation board for this product?

Thank you.
Hi,
my company is using FR60 controllers for some years now.
They are fine technically, but clearly on the way to discontinuation.
Thus, we ponder porting our ECU application to a ARM core, with a M4F looking sufficient.
I'm well aware that the FR60 is/was a Fujitsu proprietary core, and shares very little resemblance with a Cortex M core.
But since the FM4 family originated within Fujitsu as well, there is a good chance both families share common peripheral components.
In other words, was the IP of peripherals from the FR60 re-used for the FM3/FM3 family ?
Especially the CAN peripheral unit would be interesting, but timers and serial units as well.
I realized similar reuse of periphery blocks with MCUs from other vendors - often even old 8-bit periphery ends up on Cortex M4 cores.
Perhaps anyone can share some insights.
Show LessHi This is Praveen Babu,
I am getting error expression must have a const value, when i compile c code (ANSI C99 Standards)
Iam using softune compiler V6 , this compiler is having ANSI C89 Standards.
How to update Softune C/C++ compiler with ANSI C99 and later versions
