Altera SPI doesn't support programmable rate which is needed for MMC SPI, nor does Xilinx SPI. It combines transmit and receive buffer and remove unused functions. It takes only 36 LEs for SPI flash controller, or 53 LEs for MMC SPI controller in an Altera CycoloneIII SOPC project. While Altera SPI takes around 143 LEs.
Hi guys, My little story short, when I received the board I was never able to get the programmer to sucessfully program my BX bord. Neither the GUI nor the command line tool, litterally spend two days trying to make it work. I then stumbled across a wiki section on the github of TinyFPGA talking about programming the fpga with an arduino board. Never worked either.
I then decided to build my own little tools for programming the SPI Flash on the board. At the end, I was able to sucessfully flash and use my board, but after the first flash obviously I lost the bootloader (which never worked anyway). So for anybody in my situation who needs a recovery method to be able to flash the board, I put the link to the github of my flasher. It’s nothing fancy, but hey, if it can help someone that’s that. Qt based GUI for programming the TinyFPGA with an arduino - simonbeaudoin0935/TinyFPGA-Programmer. The sketch for an arduino is provided and the GUI is based on Qt so you have to download it. Just solder to the SPI pads under the board to an arduino, with a voltage divider and it’s good.
The reset button of the board must be pressed during the whole time. I soldered a wire to the pad under the board and plug it in a ground pin of the arduino.
It’s still a work in progress as I plan to implement a functionality for flashing any code at any desired address, so FPGA logic does’t have to be consumed to implement a state machine writing data at particular addresses, in case the fpga uses the rest of the abundant memory of the flash.
In your journey hacking, modding and making electronics you will bump into many a FLASH chip. Often times these store program memory, settings, data files etc. Some microcontrollers have built-in flash, but an external flash chip allows for field-updating. Also, fitting a large Flash chip inside a micro or FPGA can increase cost a lot, where-as having it be external lets the customer pick exactly the right size they need. They can range from 256 bytes up to 16 MBytes or even more! SPI Flash Standardization The good news is that just about every 8-pin Flash chip has a standard pinout and SPI interface, these tend to have the number 25 somewhere in the beginning of the part number. There are also ones that are only I2C - these will have the number 24 somewhere in the part number.
Teknik permainan bola basket. This page is just about SPI flash. As you can see, SPI flash part numbers tend to start with 'MX25' or 'W25' or 'AT25' or 'SST25' etc. The first two letters are the manufacturer name. The rest of the part number will also contain a 3 digit number that indicates the size in 'kilobits' or 'megabits'. 010 is 1-Megabit (128 KByte), 080 is 8-Megabit (1 MByte), 016 is 16-Mbit/2MByte. El capitan boot screen compatible video cards for mac pro 31 x. For smaller sizes, all 3 digits are used.
