Hi,
My smps design design spec is 300V, 0.5A .
I got design from powersim.com online(online smps design) Attached schematic
In this Primary MOSFET failing continuously . Not able to get output.
Help me on this
Thanks
Hi,
I tested Post #5 working for S25FL128L Flash chip but it's not working for S25FL128S. I think I may have problem with Erasing sectors.
So I'm debugging on it.
Thanks for the reply.
For write purpose i'm using page programming command only.
I will check once again your sequence
- - - Updated - - -
My new test sequence is
1. Read flash
2. Erase flash
3. Write flash
4. Read and verify
Thanks for the reply.
Not working sequence is
1. Sending address to flash.
2. sending data to flash
The flash write verified using read back the data again and compare with Transmitted data.
In datasheet they mentioned single byte programming is possible (In datasheet Page no : # 98)
Hi All,
I'm using S25FL128S cypress flash chip. In that single byte programming not working.
Only the sector is working.
Sector write working flow. Sector size is 4096.
1. Reading data from flash - 4096 bytes
2. Erasing the sector - 4096 bytes
3. Adding new data in read data.
