Winbond 25q32 Programmator
Replaced winbond chip, is this correct? Hi, I have a Linux receiver that wouldn't flash properly, possibly due to a dodgy bootloader and thought I would try to replace the winbond chip, I have a GQ-4x programmer that I used to use for programming TSOP and luckily had an adaptor for it to fit the winbond.I have identified a replacement chip as 25Q32FVSIG. I found knocking around some old SPANSION S25FL016A chips that were very similar except for slightly different naming conventions to some of the pins, I programmed it with my bootloader after erasing chip and put it back on the PCB, the bootloader would become corrupted so I gave up with that and got the correct part which on ebay was W25Q32. I also tried to reprogram the original chip, firstly erasing it, then writing my bootloader to it, once the chip was back in the box I was in a semi up and running state but was still misbehaving. I know have the correct chip and it is a new chip, however, when I put it in my programmer I done a blank check on it and it failed as if to say it wasn't blank, I have now read the image and saved it. What I am unsure of is, am I supposed to erase the chip before I put my booloader on or do I write straight on top of it?, I'm thinking that when I erased the original chip I erased something from it that is not supposed to be deleted, like a header or something for it.
Som e solid advice would be greatly appreciated, until than I am going to attempt to write directly to the chip without erasing and put it in and see, if that doesn't work then I will erase it forst then write the bootloader and put in to pcb, in anycase, I have dumped the chip as soon as I received it and it certainly has something on it and I have it saved. EDIT: can write to chip but will not verify, I don't think it will let me erase it, when I erase it it happens in a nano second and still reports as failed on blank check.
