Re: Button Cell Player

putsProp("Started"); This looks like it might write to the emulator STDOUT window... if true, then the program will stop here because it waits forever for the vs3emu console to become available... :roll: -Panu Nicely done, i thought it just skips fucntion if no connect registered. Now works )) Thanks

Re: Button Cell Player

Driver sst25b working well now, just forgot to change the Write func ). Now both memories work fine! Acquiring new problem: erasing and writing of firmware with all checks goes well due to modified prommer24.c. Boot record is VALID.

Re: Button Cell Player

By the way. what is recommended SPI FLASH for 16 Mbit for you, and the model doesnt matter ? The only "Hard" requirement is that opcode 03h needs to be supported for reading the flash. We've used SPI flash from Winbond, Intel, Numonyx, Macronics, Spansion etc, everything works quite well, but somet...

Re: Button Cell Player

Yes, the fix is not too big, it's fixed for example in VS1053 Uniprom version 2 and maybe in all current VSIDE prommers. The symptom is that only first byte of each 256 bytes is programmed. For the SST25xxB it is needed to give a separate write command and address for each byte. -Panu Tnx, this pro...

Re: Button Cell Player

Hi! I understand fully the difficulties, and I've talked with Pasi about your 15 modules at which time he became a little white on the face because the SD load function is probably a little bit bigger than the nand flash load function, so if many of the 15 modules are close to the 8K limit, then it...
