Hello Horatiu,
just tried current mainline U-Boot on imx6ull based board with
Env in SPI NOR. Your commit "9a9d66f5eff0"
env: add spi_flash_read_env function
breaks reading Env from SPI NOR in my case...
If I interprete your patch correct, you only read until the 2 0x0
in the env ... but for the env crc, the hole CONFIG_ENV_SIZE
must be read ... else missing for crc calculation ...
Hmm... following patch fixes for me the issue:
hs@threadripper:git [master] $ git diff env/sf.c
diff --git a/env/sf.c b/env/sf.c
index b3dec82c35..dc4b56d4a4 100644
--- a/env/sf.c
+++ b/env/sf.c
@@ -98,7 +104,7 @@ static int spi_flash_read_env(struct spi_flash *flash, u32
offset, size_t len,
u32 addr = 0;
u32 page_size = flash->page_size;
- memset(buf, 0x0, len);
+ memset(buf, 0xff, len);
for (int i = 0; i < len / page_size; ++i) {
int ret = spi_flash_read(flash, offset, page_size,
&((char *)buf)[addr]);
But if I make a bigger ENV_SIZE this may break again...
bye,
Heiko
