Someone could help me to add this device to use it with the GQ-5X

Manufacturer Toshiba
Manufacturer Part Number: TC58DVM92A5TAJO
Description FLASH: 512-MBIT (64M 8 BITS) CMOS NAND E2PROM

the only datasheet I found is this one for TC58DVM92A5TAI0

Hello, I had already read the publication, but I do not understand the last part of this calculation, referring to the example you published: K9GAG08U0E
This memory is 16GB. In your calculation comes out 2076x128x8628.
What I deduce from the calculations of several del.txt memories would be something like this: (2076x8)x128x8628


Page size is 8K + 436 for the datasheet which is 1024x8 + 436 = 8628 = 21b4h. (Use Windows calculator and selection programmer mode).
PageSize="21b4h".
Block size is based on these two lines
- Page Program : (8K + 436)Byte
- Block Erase : (1M + 54.5K)Byte
1024 (1M) / 8 = 128 = 80h
BlockSize="80h"
Now calculate the size of the flash.(Memory Cell Array : (2,076M x 110.49K) x 8bit)
2076 * 128 * 8628 = 2292701184 = 88A7D800h
