Hello,
I'm trying to add jff2 to my current project. I have qspi NAND flash
w25q128. Currently it works through the SPI(not QSPI). Operations Write,
Read and Erase Sector are working well.
control struct is:
*static rtems_jffs2_flash_control spiflash_control ={.block_size =
SPIFLASH_BLOCK_SIZE,.flash_size = SPIFLASH_SIZE,.read =
flash_read,.write = flash_write,.erase = flash_erase};*
where
*#define SPIFLASH_BLOCK_SIZE 0x1000#define SPIFLASH_SIZE (16 *
SPIFLASH_BLOCK_SIZE)*
---
When I'm trying to mount I see the following sequence:
1. read sequence for a addresses from 0x1000 to 0xF000
2. trying to erase on 0xE000
3. drop to loop with a message:
*<4>JFFS2: Failed to allocate page buffer for verifying erase at
0xe000. Refiling*
Behavior can be different if I start playing with *SPIFLASH_BLOCK_SIZE
*and *SPIFLASH_SIZE
*but in any cases by the meaning of time I see "Failed to allocate page
buffer..." message.
Could someone suggest what I'm doing wrong?
